[jira] [Created] (HBASE-18182) set HBASE_REGIONSERVER_OPTS use
UseG1GC will cause regionserver start error
Fangyuan Deng created HBASE-18182:
-------------------------------------
Summary: set HBASE_REGIONSERVER_OPTS use UseG1GC will cause regionserver start error
Key: HBASE-18182
URL: https://issues.apache.org/jira/browse/HBASE-18182
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 1.2.6, 1.3.1, 1.1.6, 2.0.0
Reporter: Fangyuan Deng
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'/''}
