             Summary: 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


When using MR2, the user classpath 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}
