[jira] [Commented] (KYLIN-4668) outOfMemery,/bin/kylin.sh
org.apache.kylin.tool.StorageCleanupJob --delete true
[ https://issues.apache.org/jira/browse/KYLIN-4668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17166081#comment-17166081 ]
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"
