when i execute "metastore.sh clean", i get a "OutOfMemoryError"

Hi, Kylin Team.

when i execute "bin/metastore.sh clean --delete true" , i get a "OutOfMemoryError" like this



java.lang.OutOfMemoryError: Java heap space
Dumping heap to java_pid4839.hprof ...
Heap dump file created [317991670 bytes in 2.120 secs]
#
# java.lang.OutOfMemoryError: Java heap space
# -XX:OnOutOfMemoryError="kill -9 %p"
#&nbsp; &nbsp;Executing /bin/sh -c "kill -9 4839"...
bin/metastore.sh: line 109:&nbsp; 4839 Killed&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ${KYLIN_HOME}/bin/kylin.sh org.apache.kylin.tool.MetadataCleanupJob "${@:2}"





i have set 'setenv.sh' file, like this


export KYLIN_JVM_SETTINGS="-Xms16g -Xmx16g -XX:MaxPermSize=512m -XX:NewSize=3g -XX:MaxNewSize=3g -XX:SurvivorRatio=4 -XX:+CMSClassUnloadingEnabled -XX:+CMSParallelRemarkEnabled -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -XX:+HeapDumpOnOutOfMemoryError -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:$KYLIN_HOME/logs/kylin.gc.$$ -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M"


Dose it means heap memory is still small?&nbsp;
