Mit Desai commented on YARN-2890:
---------------------------------
I was trying out the fix for MiniMRYarnCluster where we want to start the
timeline service only if the TIMELINE_SERVICE_ENABLED == true. But as per
current implementation of the miniCluster, it takes in a boolean when its
instance is created to decide whether to start or not to start the timeline
server.
{{public MiniMRYarnCluster(String testName, int noOfNMs, boolean enableAHS)}}
To me that seems to be a wrong way to start the timeline server. I was thinking
of removing the flag all together and start the timeline service only if the
following config is turned on.
{{YarnConfiguration.TIMELINE_SERVICE_ENABLED}}
What do you guys think of it? I am cleaning up my patch and will post it
shortly so everyone can take a look and provide their feedback.
> MiniMRYarnCluster should turn on timeline service if configured to do so
