* Interface for checking if a hostname matches the names stored inside the
* server's X.509 certificate. Correctly implements
* javax.net.ssl.HostnameVerifier, but that interface is not recommended.
* Instead we added several check() methods that take SSLSocket,
* or X509Certificate, or ultimately (they all end up calling this one),
* String. (It's easier to supply JUnit with Strings instead of mock
* SSLSession objects!)
* </p><p>Our check() methods throw exceptions if the name is
* invalid, whereas javax.net.ssl.HostnameVerifier just returns true/false.
* <p/>
* We provide the HostnameVerifier.DEFAULT, HostnameVerifier.STRICT, and
* HostnameVerifier.ALLOW_ALL implementations. We also provide the more
* specialized HostnameVerifier.DEFAULT_AND_LOCALHOST, as well as
* HostnameVerifier.STRICT_IE6. But feel free to define your own

Sebastian Hauer's original StrictSSLProtocolSocketFactory used

Parses a X.500 distinguished name for the value of the

now and should probably be done a bit more according to

I've noticed that toString() seems to do a better job than
getName() on these X500Principal objects, so I'm hoping that
addresses Sebastian's concern.
For example, getName() gives me this:

whereas toString() gives me this:

Hadoop Map Reduce Next Generation-${project.version} - Encrypted Shuffle
---
---
${maven.build.timestamp}
Hadoop MapReduce Next Generation - Encrypted Shuffle
\[ {{{./index.html}Go Back}} \]
* {Introduction}
The Encrypted Shuffle capability allows encryption of the MapReduce shuffle
using HTTPS and with optional client authentication (also known as
bi-directional HTTPS, or HTTPS with client certificates). It comprises:
* A Hadoop configuration setting for toggling the shuffle between HTTP and
HTTPS.
* A Hadoop configuration settings for specifying the keystore and truststore
properties (location, type, passwords) used by the shuffle service and the
reducers tasks fetching shuffle data.
* A way to re-load truststores across the cluster (when a node is added or
removed).
* {Configuration}
** <<core-site.xml>> Properties
To enable encrypted shuffle, set the following properties in core-site.xml of
all nodes in the cluster:
*--------------------------------------+---------------------+-----------------+
| <<Property>> | <<Default Value>> | <<Explanation>> |
*--------------------------------------+---------------------+-----------------+
| <<<hadoop.ssl.require.client.cert>>> | <<<false>>> | Whether client certificates are required |
*--------------------------------------+---------------------+-----------------+
| <<<hadoop.ssl.hostname.verifier>>> | <<<DEFAULT>>> | The hostname verifier to provide for HttpsURLConnections. Valid values are: <<DEFAULT>>, <<STRICT>>, <<STRICT_I6>>, <<DEFAULT_AND_LOCALHOST>> and <<ALLOW_ALL>> |
*--------------------------------------+---------------------+-----------------+
| <<<hadoop.ssl.keystores.factory.class>>> | <<<org.apache.hadoop.security.ssl.FileBasedKeyStoresFactory>>> | The KeyStoresFactory implementation to use |
*--------------------------------------+---------------------+-----------------+
| <<<hadoop.ssl.server.conf>>> | <<<ss-server.xml>>> | Resource file from which ssl server keystore information will be extracted. This file is looked up in the classpath, typically it should be in Hadoop conf/ directory |
*--------------------------------------+---------------------+-----------------+
| <<<hadoop.ssl.client.conf>>> | <<<ss-client.xml>>> | Resource file from which ssl server keystore information will be extracted. This file is looked up in the classpath, typically it should be in Hadoop conf/ directory |
*--------------------------------------+---------------------+-----------------+
<<IMPORTANT:>> Currently requiring client certificates should be set to false.
Refer the {{{ClientCertificates}Client Certificates}} section for details.
<<IMPORTANT:>> All these properties should be marked as final in the cluster
configuration files.
*** Example:
------
...
<property>
<name>hadoop.ssl.require.client.cert</name>
<value>false</value>
<final>true</final>
</property>
<property>
<name>hadoop.ssl.hostname.verifier</name>
<value>DEFAULT</value>
<final>true</final>
</property>
<property>
<name>hadoop.ssl.keystores.factory.class</name>
<value>org.apache.hadoop.security.ssl.FileBasedKeyStoresFactory</value>
<final>true</final>
</property>
<property>
<name>hadoop.ssl.server.conf</name>
<value>ssl-server.xml</value>
<final>true</final>
</property>
<property>
<name>hadoop.ssl.client.conf</name>
<value>ssl-client.xml</value>
<final>true</final>
</property>
...
------
** <<<mapred-site.xml>>> Properties
To enable encrypted shuffle, set the following property in mapred-site.xml
of all nodes in the cluster:
*--------------------------------------+---------------------+-----------------+
| <<Property>> | <<Default Value>> | <<Explanation>> |
*--------------------------------------+---------------------+-----------------+
| <<<mapreduce.shuffle.ssl.enabled>>> | <<<false>>> | Whether encrypted shuffle is enabled |
*--------------------------------------+---------------------+-----------------+
<<IMPORTANT:>> This property should be marked as final in the cluster
configuration files.
*** Example:
------
...
<property>
<name>mapreduce.shuffle.ssl.enabled</name>
<value>true</value>
<final>true</final>
</property>
...
------
The Linux container executor should be set to prevent job tasks from
reading the server keystore information and gaining access to the shuffle
server certificates.
Refer to Hadoop Kerberos configuration for details on how to do this.
* {Keystore and Truststore Settings}
Currently <<<FileBasedKeyStoresFactory>>> is the only <<<KeyStoresFactory>>>
implementation. The <<<FileBasedKeyStoresFactory>>> implementation uses the
following properties, in the <<ssl-server.xml>> and <<ssl-client.xml>> files,
to configure the keystores and truststores.
** <<<ssl-server.xml>>> (Shuffle server) Configuration:
The mapred user should own the <<ssl-server.xml>> file and have exclusive
read access to it.
*---------------------------------------------+---------------------+-----------------+
| <<Property>> | <<Default Value>> | <<Explanation>> |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.keystore.type>>> | <<<jks>>> | Keystore file type |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.keystore.location>>> | NONE | Keystore file location. The mapred user should own this file and have exclusive read access to it. |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.keystore.password>>> | NONE | Keystore file password |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.truststore.type>>> | <<<jks>>> | Truststore file type |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.truststore.location>>> | NONE | Truststore file location. The mapred user should own this file and have exclusive read access to it. |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.truststore.password>>> | NONE | Truststore file password |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.server.truststore.reload.interval>>> | 10000 | Truststore reload interval, in milliseconds |
*--------------------------------------+----------------------------+-----------------+
*** Example:
------
<configuration>
<!-- Server Certificate Store -->
<property>
<name>ssl.server.keystore.type</name>
<value>jks</value>
</property>
<property>
<name>ssl.server.keystore.location</name>
<value>${user.home}/keystores/server-keystore.jks</value>
</property>
<property>
<name>ssl.server.keystore.password</name>
<value>serverfoo</value>
</property>
<!-- Server Trust Store -->
<property>
<name>ssl.server.truststore.type</name>

</property>
<property>
<name>ssl.server.truststore.location</name>
<value>${user.home}/keystores/truststore.jks</value>

<value>clientserverbar</value>
</property>
<property>
<name>ssl.server.truststore.reload.interval</name>
<value>10000</value>
</property>
</configuration>
------
** <<<ssl-client.xml>>> (Reducer/Fetcher) Configuration:
The mapred user should own the <<ssl-server.xml>> file and it should have
default permissions.
*---------------------------------------------+---------------------+-----------------+
| <<Property>> | <<Default Value>> | <<Explanation>> |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.keystore.type>>> | <<<jks>>> | Keystore file type |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.keystore.location>>> | NONE | Keystore file location. The mapred user should own this file and it should have default permissions. |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.keystore.password>>> | NONE | Keystore file password |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.truststore.type>>> | <<<jks>>> | Truststore file type |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.truststore.location>>> | NONE | Truststore file location. The mapred user should own this file and it should have default permissions. |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.truststore.password>>> | NONE | Truststore file password |
*---------------------------------------------+---------------------+-----------------+
| <<<ssl.client.truststore.reload.interval>>> | 10000 | Truststore reload interval, in milliseconds |
*--------------------------------------+----------------------------+-----------------+
*** Example:

<value>10000</value>
</property>
</configuration>

* Activating Encrypted Shuffle
When you have made the above configuration changes, activate Encrypted
Shuffle by re-starting all NodeManagers.
<<IMPORTANT:>> Using encrypted shuffle will incur in a significant
performance impact. Users should profile this and potentially reserve
1 or more cores for encrypted shuffle.
* {ClientCertificates} Client Certificates
Using Client Certificates does not fully ensure that the client is a
reducer task for the job. Currently, Client Certificates (their private key)
keystore files must be readable by all users submitting jobs to the cluster.
This means that a rogue job could read such those keystore files and use
the client certificates in them to establish a secure connection with a
Shuffle server. However, unless the rogue job has a proper JobToken, it won't
be able to retrieve shuffle data from the Shuffle server. A job, using its
own JobToken, can only retrieve shuffle data that belongs to itself.
* Reloading Truststores
By default the truststores will reload their configuration every 10 seconds.
If a new truststore file is copied over the old one, it will be re-read,
and its certificates will replace the old ones. This mechanism is useful for
adding or removing nodes from the cluster, or for adding or removing trusted
clients. In these cases, the client or NodeManager certificate is added to
(or removed from) all the truststore files in the system, and the new
configuration will be picked up without you having to restart the NodeManager
daemons.
* Debugging
<<NOTE:>> Enable debugging only for troubleshooting, and then only for jobs
running on small amounts of data. It is very verbose and slows down jobs by
several orders of magnitude. (You might need to increase mapred.task.timeout
to prevent jobs from failing because tasks run so slowly.)
To enable SSL debugging in the reducers, set <<<-Djavax.net.debug=all>>> in
the <<<mapreduce.reduce.child.java.opts>>> property; for example:
------
<property>
<name>mapred.reduce.child.java.opts</name>
<value>-Xmx-200m -Djavax.net.debug=all</value>
</property>
------
You can do this on a per-job basis, or by means of a cluster-wide setting in
the <<<mapred-site.xml>>> file.
To set this property in NodeManager, set it in the <<<yarn-env.sh>>> file:
------
YARN_NODEMANAGER_OPTS="-Djavax.net.debug=all $YARN_NODEMANAGER_OPTS"
------
