HiveServer2 OnOutOfMemoryError

[#1]

Hi,

After running hive job and take a look at ps -ef | grep hive, I see messages for hiveserver2 and hivemetastore like that:

...-Xms1073741824 -Xmx1073741824 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:-CMSConcurrentMTEnabled -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:OnOutOfMemoryError=/usr/lib64/cmf/service/common/killparent.sh...

Does it means, that where is not enough memory allocated for  hiveserver2 and hivemetastore java heap size parameters?

This just means, in the case of running out of memory, execute this script.
It doesn't mean there is not enough memory.

Understood. Thanks.
