Robert Kanter commented on OOZIE-2066:
--------------------------------------
The action output should also print the classpath, what does it show?
> oozie.launcher.mapreduce.task.classpath.user.precedence is not respected

> Key: OOZIE-2066
> URL: https://issues.apache.org/jira/browse/OOZIE-2066
> Project: Oozie
> Issue Type: Bug
> Environment: yarn
> Reporter: Tim Robertson
> Priority: Critical
> Attachments: test-wf.zip
>
>
> When using MR2, the user classpath precedence is not read from the job
> configuration.
> When submitting a job, the following configuration should result in the java
> action running with the user classpath before the Hadoop jars.
> {code:xml}
> <property>
> <name>oozie.launcher.mapreduce.task.classpath.user.precedence</name>
> <value>true</value>
> </property>
> {code}
> When used in a Java action:
> {code:xml}
> <action name="run-test">
> <java>
> <job-tracker>c1n2.gbif.org:8032</job-tracker>
> <name-node>hdfs://c1n1.gbif.org:8020</name-node>
> <main-class>test.CPTest</main-class>
> </java>
> <ok to="end" />
> <error to="kill" />
> </action>
> {code}
> However, it is not...
> There is a workaround, by setting this on the task directly in the workflow:
> {code:xml}
> <action name="run-test">
> <java>
> <job-tracker>c1n2.gbif.org:8032</job-tracker>
> <name-node>hdfs://c1n1.gbif.org:8020</name-node>
> <configuration>
> <property>
> <name>oozie.launcher.mapreduce.task.classpath.user.precedence</name>
> <value>true</value>
> </property>
> </configuration>
> <main-class>test.CPTest</main-class>
> </java>
> <ok to="end" />
> <error to="kill" />
> </action>
> {code}
