> Key: HADOOP-12855
> URL: https://issues.apache.org/jira/browse/HADOOP-12855
> Project: Hadoop Common
> Issue Type: Improvement
> Components: performance
> Affects Versions: 2.8.0
> Environment: JVMs with miniHDFS and miniYarn clusters
> Reporter: Steve Loughran
> Assignee: John Zhuge
> Attachments: HADOOP-12855-001.patch
>
>
> Now that the YARN and HDFS services automatically start a JVM pause monitor, if you start up the mini HDFS and YARN clusters, with history server, you are spinning off 5 + threads, all looking for JVM pauses, all printing things out when it happens.
> We do not need these monitors in minicluster testing; they merely add load and noise to tests.
> Rather than retrofit new options everywhere, how about having a "jvm.pause.monitor.enabled" flag (default true), which, when set, starts off the monitor thread.
> That way, the existing code is unchanged, there is always a JVM pause monitor for the various services —it just isn't spinning up threads.
