CLI Mini Cluster

Hadoop Tarball

You should be able to obtain the Hadoop tarball from the release. Also, you can directly create a tarball from the source:

$ mvn clean install -DskipTests
$ mvn package -Pdist -Dtar -DskipTests -Dmaven.javadoc.skip

NOTE: You will need protoc 2.5.0 installed.

The tarball should be available in hadoop-dist/target/ directory.

 

Running the MiniCluster

From inside the root directory of the extracted tarball, you can start the CLI MiniCluster using the following command:

$ bin/hadoop jar ./share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-2.7.1-tests.jar minicluster -rmport RM_PORT -jhsport JHS_PORT

In the example command above, RM_PORT and JHS_PORT should be replaced by the user’s choice of these port numbers. If not specified, random free ports will be used.
