QiangZhang commented on KYLIN-4668:
-----------------------------------
You can use a tool to analyze the dump file and locate the code that generated
the OOM。
I guess hbase caused the OOM，you can try setting "hbase-env.sh " to scale up
JVM memory,such as:
export HBASE_OPTS="-Xmx268435456 -XX:+HeapDumpOnOutOfMemoryError
-XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -Djava.net.preferIPv4Stack=true
$HBASE_OPTS"
> outOfMemery,/bin/kylin.sh org.apache.kylin.tool.StorageCleanupJob --delete
> true
