Bright:Testing Hadoop

Bright's Hadoop Tests

Automatic tests:

cd /cm/local/apps/cluster-tools/hadoop/
./cm-hadoop-tests.sh <instance> # instance is boston-hdfs in our case

End User test runs:

• Firstly, you must give the user access to the Hadoop instance:

 [bright70->user[fred]]% set hadoophdfsaccess boston-hdfs; commit

• Then the user can run the tests like this:

[fred@bright70 ~]$ module load hadoop/hdfs1/Hortonworks/2.6.0.2.2.0.0-2041
[fred@bright70 ~]$ module load zookeeper/hdfs1/Hortonworks/3.4.6.2.2.0.0-2041
[fred@bright70 ~]$ module load hbase/hdfs1/Hortonworks/0.98.4.2.2.0.0-2041-hadoop2
[fred@bright70 ~]$ hadoop jar $HADOOP_PREFIX/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar pi 1 5
