Subject [jira] [Commented] (MAPREDUCE-6507) TestRMNMInfo fails intermittently
Date Fri, 09 Oct 2015 09:57:27 GMT

Rohith Sharma K S commented on MAPREDUCE-6507:
----------------------------------------------

Looks like MiniMRYarnCluster start is not waiting for all the NodeManagers to start and register
with RM which causes random failure depends on the machine load.
