Subject [jira] [Commented] (MAPREDUCE-6189) TestMRTimelineEventHandling fails in trunk
Date Wed, 08 Apr 2015 16:24:13 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14485468#comment-14485468

Junping Du commented on MAPREDUCE-6189:
---------------------------------------

>From the log below, it get failed because AM cannot get enough resource to get start.
{noformat}
2015-04-08 16:23:53,338 INFO  [ResourceManager Event Processor] capacity.LeafQueue (LeafQueue.java:activateApplications(613))
- not starting application as amIfStarted exceeds amLimit
{noformat}
This issue looks like related to YARN-2637. 
After setting CapacitySchedulerConfiguration.MAXIMUM_APPLICATION_MASTERS_RESOURCE_PERCENT
to 1.0, the job can be partially succeed. However, it still get failed in launching more applications
as amIfStarted won't get decreased even last application get finished. Suspect some bug there
for YARN-2637.
