Hi Shaofeng Shi,
I have set KYLIN_JVM_SETTINGS="-Xms16g -Xmx16g" in setenv.sh, but it fail. Can metadata be larger than 16g? Thanks for reply. ------------------ ???????? ------------------ ??????: "ShaoFeng Shi"<[email protected]>; ????????: 2019??11??22??(??????) ????3:18 ??????: "user"<[email protected]>; ????: Re: metastore clean OutOfMemoryError hi Huangpeng, I guess your JVM heap is small or your Kylin metadata is big. You can try to increase the java heap in "bin/setenv.sh" Best regards, Shaofeng Shi ??????

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" # Executing /bin/sh -c "kill -9 4839"... bin/metastore.sh: line 109: 4839 Killed ${KYLIN_HOME}/bin/kylin.sh org.apache.kylin.tool.MetadataCleanupJob "${@: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?
