Subject [jira] [Commented] (YARN-4983) JVM and UGI metrics disappear after RM is once transitioned to standby mode
Date Tue, 26 Apr 2016 08:38:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-4983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15257749#comment-15257749
] 

Junping Du commented on YARN-4983:
----------------------------------

bq. Due to the amount of work to refactor RM HA, maybe we want to resolve that in a separate
JIRA?
Sounds good. Will file a separate JIRA to track this.

Three UT test failures are not related, HADOOP-12687 and YARN-4947 are filed before to track
them.

+1. Patch LGTM. Will commit it shortly if no further comments from others.

> When get transitioned to standby, the RM will shutdown the existing metric system and
relaunch a new one. This will cause the jvm metrics and ugi metrics to miss in the new metric
system.
