How to enable debug logger in Resource Manager

hi, all

I found a lot of codes in YARN's Resource Manager:

if (LOG.isDebugEnabled()) {
        LOG.debug(...)

}

My question is how to enable this to log more information.


Thanks!

Wei

Set log level to DEBUG to enable it.
There are several ways to set the log level of a class. My favorite way is
to change it by visiting https://RM-address:port/logLevel.

Best,

Yufei
