Jonathan Hsieh resolved HBASE-5276.
-----------------------------------
Resolution: Duplicate
> PerformanceEvaluation does not set the correct classpath for MR because it
> lives in the test jar
> ------------------------------------------------------------------------------------------------
>
> Key: HBASE-5276
> URL: https://issues.apache.org/jira/browse/HBASE-5276
> Project: HBase
> Issue Type: Bug
> Components: test
> Affects Versions: 0.90.4
> Reporter: Tim Robertson
> Assignee: Jonathan Hsieh
> Priority: Minor
>
> Note: This was discovered running the CDH version hbase-0.90.4-cdh3u2
> Running the PerformanceEvaluation as follows:
> $HADOOP_HOME/bin/hadoop org.apache.hadoop.hbase.PerformanceEvaluation scan 5
> fails because the MR tasks do not get the HBase jar on the CP, and thus hit
> ClassNotFoundExceptions.
> The job gets the following only:
> file:/Users/tim/dev/hadoop/hbase-0.90.4-cdh3u2/hbase-0.90.4-cdh3u2-tests.jar
>
> file:/Users/tim/dev/hadoop/hadoop-0.20.2-cdh3u2/hadoop-core-0.20.2-cdh3u2.jar
>
> file:/Users/tim/dev/hadoop/hbase-0.90.4-cdh3u2/lib/zookeeper-3.3.3-cdh3u2.jar
> The RowCounter etc all work because they live in the HBase jar, not the test
> jar, and they get the following
> file:/Users/tim/dev/hadoop/hbase-0.90.4-cdh3u2/lib/guava-r06.jar
>
> file:/Users/tim/dev/hadoop/hadoop-0.20.2-cdh3u2/hadoop-core-0.20.2-cdh3u2.jar
> file:/Users/tim/dev/hadoop/hbase-0.90.4-cdh3u2/hbase-0.90.4-cdh3u2.jar
>
> file:/Users/tim/dev/hadoop/hbase-0.90.4-cdh3u2/lib/zookeeper-3.3.3-cdh3u2.jar
> Presumably this relates to
> job.setJarByClass(PerformanceEvaluation.class);
> ...
> TableMapReduceUtil.addDependencyJars(job);
> A (cowboy) workaround to run PE is to unpack the jars, and copy the
> PerformanceEvaluation* classes building a patched jar.
