Tsuyoshi Ozawa commented on YARN-2890: -------------------------------------- [~mitdesai] thank you for updating a patch! +1 for the change itself to make it configurable. {quote} 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. {quote} I don't understand the context - why you'd like to make the flag off by default? Could you clarify it? IMO, it would be enough to make it configurable. > MiniMRYarnCluster should turn on timeline service if configured to do so > ------------------------------------------------------------------------ > > Key: YARN-2890 > URL: https://issues.apache.org/jira/browse/YARN-2890 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.6.0 > Reporter: Mit Desai > Assignee: Mit Desai > Attachments: YARN-2890.patch, YARN-2890.patch, YARN-2890.patch, > YARN-2890.patch, YARN-2890.patch > > > Currently the MiniMRYarnCluster does not consider the configuration value for > enabling timeline service before starting.
