    Description

      The hadoop-common carries in it a nifty thread that prints GC or non-GC pauses within the JVM if it exceeds a specific threshold.

      This has been immeasurably useful in supporting several clusters, in identifying GC or other form of process pauses to be the root cause of some event being investigated.

      The HMS and HS2 daemons are good targets for running similar threads within it. It can be loaded in an if-available style.
