-----------------------------
Summary: Add JvmPauseMonitor threads to HMS and HS2 daemons
Key: HIVE-9870
URL: https://issues.apache.org/jira/browse/HIVE-9870
Project: Hive
Issue Type: Improvement
Components: HiveServer2, Metastore
Affects Versions: 1.1
Reporter: Harsh J
Assignee: Harsh J
Priority: Minor
The hadoop-common carries in it a nifty thread that prints GC or non-GC pauses
within the JVM if it exceeds a specific threshold.
This has been immeasurably useful in supporting several clusters, in
identifying GC or other form of process pauses to be the root cause of some
event being investigated.
The HMS and HS2 daemons are good targets for running similar threads within it.
It can be loaded in an if-available style.
