To compile Hadoop Mapreduce next following, do the following:
|
|
|
|
Step 1) Install dependencies for yarn
|
|
|
|
See http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-mapreduce/hadoop-yarn/README
|
|
Make sure protbuf library is in your library path or set: export LD_LIBRARY_PATH=/usr/local/lib
|
|
|
|
Step 2) Checkout
|
|
|
|
svn checkout http://svn.apache.org/repos/asf/hadoop/common/trunk
|
|
|
|
Step 3) Build common
|
|
|
|
Go to common directory - choose your regular common build command
|
|
Example: mvn clean install package -Pbintar -DskipTests
|
|
|
|
Step 4) Build HDFS
|
|
|
|
Go to hdfs directory
|
|
ant veryclean mvn-install -Dresolvers=internal
|
|
|
|
Step 5) Build yarn and mapreduce
|
|
|
|
Go to mapreduce directory
|
|
export MAVEN_OPTS=-Xmx512m
|
|
|
|
mvn clean install assembly:assembly -DskipTests
|
|
|
|
Copy in build.properties if appropriate - make sure eclipse.home not set
|
|
ant veryclean tar -Dresolvers=internal
|
|
|
|
You will see a tarball in
|
|
ls target/hadoop-mapreduce-0.23.0-SNAPSHOT-all.tar.gz
|
|
|
|
Step 6) Untar the tarball in a clean and different directory.
|
|
say YARN_HOME.
|
|
|
|
Make sure you aren't picking up avro-1.3.2.jar, remove:
|
|
$HADOOP_COMMON_HOME/share/hadoop/common/lib/avro-1.3.2.jar
|
|
$YARN_HOME/lib/avro-1.3.2.jar
|
|
|
|
Step 7)
|
|
Install hdfs/common and start hdfs
|
|
|
|
To run Hadoop Mapreduce next applications:
|
|
|
|
Step 8) export the following variables to where you have things installed:
|
|
You probably want to export these in hadoop-env.sh and yarn-env.sh also.
|
|
|
|
export HADOOP_MAPRED_HOME=<mapred loc>
|
|
export HADOOP_COMMON_HOME=<common loc>
|
|
export HADOOP_HDFS_HOME=<hdfs loc>
|
|
export YARN_HOME=directory where you untarred yarn
|
|
export HADOOP_CONF_DIR=<conf loc>
|
|
export YARN_CONF_DIR=$HADOOP_CONF_DIR
|
|
|
|
Step 9) Setup config: for running mapreduce applications, which now are in user land, you need to setup nodemanager with the following configuration in your yarn-site.xml before you start the nodemanager.
|
|
<property>
|
|
<name>nodemanager.auxiluary.services</name>
|
|
<value>mapreduce.shuffle</value>
|
|
</property>
|
|
|
|
<property>
|
|
<name>nodemanager.aux.service.mapreduce.shuffle.class</name>
|
|
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
|
|
</property>
|
|
|
|
Step 10) Modify mapred-site.xml to use yarn framework
|
|
<property>
|
|
<name> mapreduce.framework.name</name>
|
|
<value>yarn</value>
|
|
</property>
|
|
|
|
Step 11) Create the following symlinks in $HADOOP_COMMON_HOME/share/hadoop/common/lib
|
|
|
|
ln -s $YARN_HOME/modules/hadoop-mapreduce-client-app-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-yarn-api-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-mapreduce-client-common-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-yarn-common-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-mapreduce-client-core-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-yarn-server-common-0.23.0-SNAPSHOT.jar .
|
|
ln -s $YARN_HOME/modules/hadoop-mapreduce-client-jobclient-0.23.0-SNAPSHOT.jar .
|
|
|
|
Step 12) cd $YARN_HOME
|
|
|
|
Step 13) bin/yarn-daemon.sh start resourcemanager
|
|
|
|
Step 14) bin/yarn-daemon.sh start nodemanager
|
|
|
|
Step 15) bin/yarn-daemon.sh start historyserver
|
|
|
|
Step 16) You are all set, an example on how to run a mapreduce job is:
|
|
cd $HADOOP_MAPRED_HOME
|
|
ant examples -Dresolvers=internal
|
|
$HADOOP_COMMON_HOME/bin/hadoop jar $HADOOP_MAPRED_HOME/build/hadoop-mapreduce-examples-0.23.0-SNAPSHOT.jar randomwriter -Dmapreduce.job.user.name=$USER -Dmapreduce.clientfactory.class.name=org.apache.hadoop.mapred.YarnClientFactory -Dmapreduce.randomwriter.bytespermap=0.23.000 -Ddfs.blocksize=536870912 -Ddfs.block.size=536870912 -libjars $YARN_HOME/modules/hadoop-mapreduce-client-jobclient-0.23.0-SNAPSHOT.jar output
|
|
|
|
The output on the command line should be almost similar to what you see in the JT/TT setup (Hadoop 0.20/0.21)
