YARN -- Debug messages in logs

[Krishna Kishore Bonagiri]

Hi,

  How can I get the debug log messages from RM and other daemons?

For example,

   Currently I could see messages from LOG.info() only, i.e. something like
this:

    LOG.info(event.getContainerId() + " Container Transitioned from " +
oldState + " to " + getState());

How can I get those from LOG.debug() ? I mean the following kind of
messages ...

    LOG.debug("Processing " + event.getContainerId() + " of type " +
event.getType());


Thanks,
Kishore
