Maybe in Hadoop 3.x converted to an exception. > Distributed cache conflicts breaks backwards compatability > ---------------------------------------------------------- > > Key: MAPREDUCE-4549 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4549 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.3 > Reporter: Robert Joseph Evans > Assignee: Robert Joseph Evans > Priority: Critical > Attachments: MR-4549-branch-0.23.txt > > > I recently put in MAPREDUCE-4503 which went a bit too far, and broke > backwards compatibility with 1.0 in distribtued cache entries. instead of > changing the behavior of the distributed cache to more closely match 1.0 > behavior I want to just change the exception to a warning message informing > the users that it will become an error in 2.0 -- This message is automatically generated by JIRA.
