Vinod Kumar Vavilapalli commented on MAPREDUCE-3426: ---------------------------------------------------- Mostly looks good. Minor comments on the patch. - Jobimpl changes: Not this patch's fault, duplicate comment starting "User has overall veto power over uberization" - RMCommunicator.stop() is still not thread-safe/idempotent - the shutdown hook and the stop-event handling may both find the volatile boolean be true and proceed. This method needs synchronization. - JobStatus constructors - in both mapred and map reduce classes - need to backwards compatible. > uber-jobs tried to write outputs into wrong dir > ----------------------------------------------- > > Key: MAPREDUCE-3426 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3426 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: mrv2 > Affects Versions: 0.23.0, 0.24.0 > Reporter: Hitesh Shah > Fix For: 0.23.1 > > Attachments: MR-3426.1.patch, MR-3426.2.patch > > > Incorrect setup of the uber tasks causes tasks to try to write intermidiate > outputs into dirs that the user does not have permissions to write to on a > secure cluster. -- This message is automatically generated by JIRA.
