Nick Dimiduk commented on HBASE-9630:
-------------------------------------
Can you reference the hadoop ticket(s) that add this feature? Can we not just
use the hadoop JvmPauseMonitor directly? At the very least, please include the
source hadoop class and svn revision number in the javadoc for JvmPauseMonitor.
> Add thread which detects JVM pauses like HADOOP's
