Hi

The documentation for a shell/java action could be more clear in how
configure the task.

>From http://oozie.apache.org/docs/4.0.0/DG_ShellActionExtension.html :

> Shell *launcher* configuration can be specified with a file, using the
> job-xml element, and inline, using the configuration elements.

However it doesn't say anything about you need to add "oozie.launcher" as a
prefix for the configuration in order to apply it on the launcher task.

Has that intentionally been left out or did we miss something?


For example, the parameter for increasing the memory for a mapper task is:

<configuration>
  <property>
    <name>*mapreduce.map.memory.m*b</name>
    <value>6144</value>
  </property>
</configuration>


But since the shell/java command is executed in the launcher task, the
configuration is actually:

<configuration>
  <property>
    <name*>oozie.launcher.mapreduce.map.memory.mb*</name>
    <value>6144</value>
  </property>
</configuration>
