Can LOG.isDebugEnabled for debugging commands be set manually on the CLI?

Can LOG.isDebugEnabled for debugging commands be set manually on the CLI?

Explorer

Looking to see if LOG.isDebugEnabled can be switch "ON" when running shell command that invokes a Java Class object. I don't want to go about messing with Ambari or logj4 for a quick debug test. Is this possible?

Trying to debug:

yarn scmadmin

@Michael DeGuzis

Do you mean client side logging?

Can you try exporting the following variable first and then try running your command:

 export HADOOP_ROOT_LOGGER=debug,console

.

Similarly for Yarn:

 export YARN_ROOT_LOGGER=DEBUG,console

.
