Siddharth Seth commented on TEZ-2225:
-------------------------------------
The source string will always be created if we remove the isDebugEnabled checks
? Is the JVM taking care of interning them - or maybe slf4j itself ?
I'd be especially vary about debug statements which are in a loop.
> Remove instances of LOG.isDebugEnabled
