Bikas Saha commented on YARN-514: --------------------------------- For MAPREDUCE-5140 please check for uses of both NEW and SUBMITTED in order to find out places where NEW_SAVING would need to be handled. > Delayed store operations should not result in RM unavailability for app > submission > ---------------------------------------------------------------------------------- > > Key: YARN-514 > URL: https://issues.apache.org/jira/browse/YARN-514 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Bikas Saha > Assignee: Zhijie Shen > Attachments: YARN-514.1.patch, YARN-514.2.patch, YARN-514.3.patch > > > Currently, app submission is the only store operation performed synchronously > because the app must be stored before the request returns with success. This > makes the RM susceptible to blocking all client threads on slow store > operations, resulting in RM being perceived as unavailable by clients. -- This message is automatically generated by JIRA.
