Summary: Port Hadoop's new GcTimeMonitor
Key: HBASE-19238
URL: https://issues.apache.org/jira/browse/HBASE-19238
Project: HBase
Issue Type: Improvement
Reporter: Andrew Purtell
Priority: Minor
We borrowed Hadoop's JvmPauseMonitor some time ago. On HADOOP-14960 (Add GC
time percentage monitor/alerter), Hadoop added a new GcTimeMonitor, which seems
useful:
{code}
/**
* This class monitors the percentage of time the JVM is paused in GC within
* the specified observation window, say 1 minute. The user can provide a
* hook which will be called whenever this percentage exceeds the specified
* threshold.
*/
{code}
