Subject [jira] [Commented] (HIVE-16343) LLAP: Publish YARN's ProcFs based memory usage to metrics for monitoring
Date Mon, 24 Apr 2017 18:19:05 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15981608#comment-15981608

Siddharth Seth commented on HIVE-16343:
---------------------------------------

Getting access to the PID. Is there an easier and more reliable way to do this, instead of
relying on a pid file. Tez/YARN use the following - While launching the process. environment.put("JVM_PID",
"$$") / export. Within the process - System.getenv().get("JVM_PID").

If retaining the current method of accessing the pid file, please move to a helper class.
The daemon class is getting a little noisy.

May want to introduce a config for which process monitor to use, instead of relying on a YARN
configuration.

How often will the metrics be collected?
