    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&nbsp;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?
