+ Swift Filesystem Client for Apache Hadoop +

+ +

Introduction

+ +
This package provides support in Apache Hadoop for the OpenStack Swift + Key-Value store, allowing client applications -including MR Jobs- to + read and write data in Swift. +
+ +
Design Goals
+
    +
  1. Give clients access to SwiftFS files, similar to S3n:
    2. +
  2. maybe: support a Swift Block store -- at least until Swift's + support for >5GB files has stabilized. +
    3. +
  3. Support for data-locality if the Swift FS provides file location information
    4. +
  4. Support access to multiple Swift filesystems in the same client/task.
    5. +
  5. Authenticate using the Keystone APIs.
    6. +
  6. Avoid dependency on unmaintained libraries.
    7. +
+ + +

Supporting multiple Swift Filesystems

+ +The goal of supporting multiple swift filesystems simultaneously changes how +clusters are named and authenticated. In Hadoop's S3 and S3N filesystems, the "bucket" into +which objects are stored is directly named in the URL, such as +s3n://bucket/object1. The Hadoop configuration contains a +single set of login credentials for S3 (username and key), which are used to +authenticate the HTTP operations. + +For swift, we need to know not only which "container" name, but which credentials +to use to authenticate with it -and which URL to use for authentication. + +This has led to a different design pattern from S3, as instead of simple bucket names, +the hostname of an S3 container is two-level, the name of the service provider +being the second path: swift://bucket.service/ + +The service portion of this domainame is used as a reference into +the client settings -and so identify the service provider of that container. + + +

Testing

+ +
+ The client code can be tested against public or private Swift instances; the + public services are (at the time of writing -January 2013-), Rackspace and + HP Cloud. Testing against both instances is how interoperability + can be verified. +

It stores + arbitrary binary objects by name in a . + + The Hadoop Swift filesystem library adds another concept, the , which + defines which Swift blobstore hosts a container -and how to connect to it. + +** Containers and Objects + + * Containers are created by users with accounts on the Swift filestore, and hold + . + + * Objects can be zero bytes long, or they can contain data. + + * Objects in the container can be up to 5GB; there is a special support for + larger files than this, which merges multiple objects in to one. + + * Each object is referenced by it's ; there is no notion of directories. + + * You can use any characters in an object name that can be 'URL-encoded'; the + maximum length of a name is 1034 characters -after URL encoding. + + * Names can have <<>> characters in them, which are used to create the illusion of + a directory structure. For example <<>>. Even though this looks + like a directory, . There is no requirement to have + any entries in the container called <<>> or <<>> + + * That said. if the container has zero-byte objects that look like directory + names above other objects, they can pretend to be directories. Continuing the + example, a 0-byte object called <<>> would tell clients that it is a + directory while <<>> or <<>> were present. This creates an + illusion of containers holding a filesystem. + + Client applications talk to Swift over HTTP or HTTPS, reading, writing and + deleting objects using standard HTTP operations (GET, PUT and DELETE, + respectively). There is also a COPY operation, that creates a new object in the + container, with a new name, containing the old data. There is no rename + operation itself, objects need to be copied -then the original entry deleted. + +** Eventual Consistency + + The Swift Filesystem is *eventually consistent*: an operation on an object may + not be immediately visible to that client, or other clients. This is a + consequence of the goal of the filesystem: to span a set of machines, across + multiple datacenters, in such a way that the data can still be available when + many of them fail. (In contrast, the Hadoop HDFS filesystem is *immediately + consistent*, but it does not span datacenters.) + + Eventual consistency can cause surprises for client applications that expect + immediate consistency: after an object is deleted or overwritten, the object + may still be visible -or the old data still retrievable. The Swift Filesystem + client for Apache Hadoop attempts to handle this, in conjunction with the + MapReduce engine, but there may be still be occasions when eventual consistency + causes surprises. + +** Non-atomic "directory" operations. + + Hadoop expects some + operations to be atomic, especially <<>>, which is something + the MapReduce layer relies on to commit the output of a job, renaming data + from a temp directory to the final path. Because a rename + is implemented as a copy of every blob under the directory's path, followed + by a delete of the originals, the intermediate state of the operation + will be visible to other clients. If two Reducer tasks to rename their temp + directory to the final path, both operations may succeed, with the result that + output directory contains mixed data. This can happen if MapReduce jobs + are being run with enabled and Swift used as the direct output + of the MR job (it can also happen against Amazon S3). + + Other consequences of the non-atomic operations are: + + 1. If a program is looking for the presence of the directory before acting + on the data -it may start prematurely. This can be avoided by using + other mechanisms to co-ordinate the programs, such as the presence of a file + that is written any bulk directory operations. + + 2. A <<>> or <<>> operation may include files added under + the source directory tree during the operation, may unintentionally delete + it, or delete the 0-byte swift entries that mimic directories and act + as parents for the files. Try to avoid doing this. + + The best ways to avoid all these problems is not using Swift as + the filesystem between MapReduce jobs or other Hadoop workflows. It + can act as a source of data, and a final destination, but it doesn't meet + all of Hadoop's expectations of what a filesystem is -it's a . + +* Working with Swift Object Stores in Hadoop + + Once installed, the Swift FileSystem client can be used by any Hadoop application + to read from or write to data stored in a Swift container. + + Data stored in Swift can be used as the direct input to a MapReduce job + -simply use the <<>> URL (see below) to declare the source of the data. + + This Swift Filesystem client is designed to work with multiple + Swift object stores, both public and private. This allows the client to work + with different clusters, reading and writing data to and from either of them. + + It can also work with the same object stores using multiple login details. + + These features are achieved by one basic concept: using a service name in + the URI referring to a swift filesystem, and looking up all the connection and + login details for that specific service. Different service names can be defined + in the Hadoop XML configuration file, so defining different clusters, or + providing different login details for the same object store(s). + + +** Swift Filesystem URIs + + Hadoop uses URIs to refer to files within a filesystem. Some common examples + are: + ++-- + local://etc/hosts + hdfs://cluster1/users/example/data/set1 + hdfs://cluster2.example.org:8020/users/example/data/set1 ++-- + + The Swift Filesystem Client adds a new URL type <<>>. In a Swift Filesystem + URL, the hostname part of a URL identifies the container and the service to + work with; the path the name of the object. Here are some examples + ++-- + swift://container.rackspace/my-object.csv + swift://data.hpcloud/data/set1 + swift://dmitry.privatecloud/out/results ++-- + + In the last two examples, the paths look like directories: it is not, they are + simply the objects named <<>> and <<>> respectively. + +** Installing + + The <<>> JAR must be on the classpath of the Hadoop program trying to + talk to the Swift service. If installed in the classpath of the Hadoop + MapReduce service, then all programs started by the MR engine will pick up the + JAR automatically. This is the easiest way to give all Hadoop jobs access to + Swift. + + Alternatively, the JAR can be included as one of the JAR files that an + application uses. This lets the Hadoop jobs work with a Swift object store even + if the Hadoop cluster is not pre-configured for this. + + The library also depends upon the Apache HttpComponents library, which + must also be on the classpath. + +** Configuring + + To talk to a swift service, the user must must provide: + + [[1]] The URL defining the container and the service. + + [[1]] In the cluster/job configuration, the login details of that service. + + Multiple service definitions can co-exist in the same configuration file: just + use different names for them. + +*** Example: Rackspace US, in-cluster access using API key + + This service definition is for use in a Hadoop cluster deployed within Rackspace's + US infrastructure. + ++-- + + fs.swift.service.rackspace.auth.url + https://auth.api.rackspacecloud.com/v2.0/tokens + Rackspace US (multiregion) + + + + fs.swift.service.rackspace.username + user4 + + + + fs.swift.service.rackspace.region + DFW + + + + fs.swift.service.rackspace.apikey + fe806aa86dfffe2f6ed8 + ++-- + + Here the API key visible in the account settings API keys page is used to log + in.

The tests expect exclusive access + to this container -do not keep any other data on it, or expect it + to be preserved. + ++-- + + test.fs.swift.name + swift://test.myswift/ + ++-- + + In the base hadoop directory, run: + ++-- + mvn clean install -DskipTests ++-- + + This builds a set of Hadoop JARs consistent with the <<>> + module that is about to be tested. + + In the <<>> directory run + ++-- + mvn test -Dtest=TestSwiftRestClient ++-- + + This runs some simple tests which include authenticating + against the remote swift service. If these tests fail, so will all + the rest. If it does fail: check your authentication. + + Once this test succeeds, you can run the full test suite + ++-- + mvn test ++-- + + Be advised that these tests can take an hour or more, especially against a + remote Swift service -or one that throttles bulk operations. + + Once the <<>> file is in place, the <<>> runs from + the Hadoop source base directory will automatically run these OpenStack tests + While this ensures that no regressions have occurred, it can also add significant + time to test runs, and may run up bills, depending on who is providing\ + the Swift storage service. We recommend having a separate source tree + set up purely for the Swift tests, and running it manually or by the CI tooling + at a lower frequency than normal test runs. + + Finally: Apache Hadoop is an open source project. Contributions of code + -including more tests- are very welcome. diff --git a/hadoop-tools/hadoop-openstack/src/site/site.xml b/hadoop-tools/hadoop-openstack/src/site/site.xml new file mode 100644 index 0000000000..97784bd4ad --- /dev/null +++ b/hadoop-tools/hadoop-openstack/src/site/site.xml @@ -0,0 +1,46 @@ + + + + + + + org.apache.maven.skins + maven-stylus-skin + 1.2 + + + + + + + + + diff --git a/hadoop-tools/hadoop-openstack/src/test/java/org/apache/hadoop/fs/swift/AcceptAllFilter.java b/hadoop-tools/hadoop-openstack/src/test/java/org/apache/hadoop/fs/swift/AcceptAllFilter.java new file mode 100644 index 0000000000..16c9da2577 --- /dev/null +++ b/hadoop-tools/hadoop-openstack/src/test/java/org/apache/hadoop/fs/swift/AcceptAllFilter.java @@ -0,0 +1,31 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
