Jason Lowe commented on YARN-357: --------------------------------- TestRMWebServices failure is likely unrelated, see HADOOP-9246. > App submission should not be synchronized > ----------------------------------------- > > Key: YARN-357 > URL: https://issues.apache.org/jira/browse/YARN-357 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 0.23.3, 3.0.0, 2.0.0-alpha > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Attachments: YARN-357.patch, YARN-357.patch > > > MAPREDUCE-2953 fixed a race condition with querying of app status by making > {{RMClientService#submitApplication}} synchronously invoke > {{RMAppManager#submitApplication}}. However, the {{synchronized}} keyword was > also added to {{RMAppManager#submitApplication}} with the comment: > bq. I made the submitApplication synchronized to keep it consistent with the > other routines in RMAppManager although I do not believe it needs it since > the rmapp datastructure is already a concurrentMap and I don't see anything > else that would be an issue. > It's been observed that app submission latency is being unnecessarily > impacted. -- This message is automatically generated by JIRA.
