Hi,

Yes, I tried to overwrite the following:
kylin.job.mr.config.override.mapreduce.map.java.opts -Xmx256000m
kylin.job.mr.config.override.mapreduce.map.memory.mb 320000
kylin.job.mr.config.override.mapreduce.reduce.memory.mb 640000
kylin.job.mr.config.override.mapreduce.reduce.java.opts-Xmx512000m

and increase set env :

export KYLIN_JVM_SETTINGS="-Xms8g -Xmx300g -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.%p -XX:+UseGCLogFileRotation
-XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M
-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap"

still getting errors as if i have not changed the RAM.
and again the machine has 1.5 TB RAM.

Please advice, any help will be appreciated.

Thanks
Omid
