Description

Oozie per default outputs debug information about the Shell Action such as command, arguments and environment variables which is then visible in the Yarn logs. This is indeed a nice feature for debugging.

However, to do so it uses System.out.print which makes it impossible to configure this behavior. It would be better to use a Logger class for this, such that this behavior can be tuned in the Oozie job/action configuration.

In Oozie 4.2. the problematic function is located here https://github.com/apache/oozie/blob/branch-4.2/sharelib/oozie/src/main/java/org/apache/oozie/action/hadoop/ShellMain.java#L244 - however the problem still exists on the master branch as well.
