bq. Region Server Crashes with below ERROR, Looks like some issues with GC configuration ? bq. 2018-08-09 14:54:26,104 INFO org.apache.hadoop.hbase.util.JvmPauseMonitor: Detected pause in JVM or host machine (eg GC): pause of approximately 6173ms bq. GC pool 'ParNew' had collection(s): count=2 time=114ms bq. GC pool 'ConcurrentMarkSweep' had collection(s): count=1 time=6262ms
A 6-second pause cannot result in a timeout with zookeeper(zookeeper.session.timeout) and may not be the reason for regionserver failure. Check for large pauses or errors(with FATAL/ERROR) in logs as Josh said.
