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

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

The second was what I was looking for. Thanks!
