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'/''} fi fi -- This message was sent by Atlassian JIRA (v6.3.15#6346)
