    Description

      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.
