-----------------------------------
Summary: Ensure one JVMPauseMonitor thread per JVM
Key: HADOOP-12946
URL: https://issues.apache.org/jira/browse/HADOOP-12946
Project: Hadoop Common
Issue Type: Improvement
Reporter: John Zhuge
Assignee: John Zhuge
Priority: Minor
Ensure at most one JVMPauseMonitor thread is running per JVM when there are
multiple JVMPauseMonitor instances, e.g., in mini clusters. This will prevent
redundant GC pause log messages while still maintaining one monitor thread
running.
This is a different way to fix HADOOP-12855.
