> when we set in hbase-env.sh to use G1GC HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:+UseG1GC -Xms96g -Xmx96g -XX:MaxGCPauseMillis=100"
> then run ./hbase-daemon.sh start regionserver
> Conflicting collector combinations in option list; please refer to the release notes for the combinations allowed
> Error: Could not create the Java Virtual Machine.
> Error: A fatal exception has occurred. Program will exit.
> because the HBASE_OPTS default use CMS and is conflicted with HBASE_REGIONSERVER_OPTS
> so I add a patch to modify bin/hbase like this
> elif [ "$COMMAND" = "regionserver" ] ; then
>   CLASS='org.apache.hadoop.hbase.regionserver.HRegionServer'
>   if [ "$1" != "stop" ] ; then
>     HBASE_OPTS="$HBASE_OPTS $HBASE_REGIONSERVER_OPTS"
>     if [[ $HBASE_REGIONSERVER_OPTS == *UseG1GC*  ]] ; then
>       HBASE_OPTS=${HBASE_OPTS/'-XX:+UseConcMarkSweepGC'/''}
>     fi
>   fi
