Description

We currently document how to propagate the delegation in the Java action:
https://oozie.apache.org/docs/4.0.1/WorkflowFunctionalSpec.html#a3.2.7_Java_Action

If users want to run CLI commands from the Shell action (e.g. hadoop fs ...), we should provide similar instructions:

export HADOOP_OPTS="-Dmapreduce.job.credentials.binary=$HADOOP_TOKEN_FILE_LOCATION"
hadoop fs ...
