Subject [jira] [Commented] (YARN-5662) Provide an option to enable ContainerMonitor
Date Fri, 23 Sep 2016 17:38:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5662?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15517071#comment-15517071
] 

Varun Saxena commented on YARN-5662:
------------------------------------

* In the call to GenericTestUtils#waitFor, the 2nd and 3rd parameters (500 and 200) should
be interchanged.
* The test failure seems related. I think we need to shutdown DefaultMetricsSystem or simply
use another container ID in the test to get rid of the error.

> Currently, if vmem/pmem check is not enabled, ContainerMonitor would not run.  In certain
cases, ContainerMonitor also needs to run to monitor things like container-metrics.
