Koji Noguchi commented on YARN-1036: ------------------------------------ When reading MAPREDUCE-4342 initially, I didn't understand why the files were deleted in the first place. Until recently, when we started seeing inconsistent distributed cache after we enabled Disk-Fail-In-Place(MAPREDUCE-2413). NodeManager/TaskTracker keeps on running even after finding bad disks without throwing away distributed cache entries coming from those disks resulting in incomplete set of distributed cache available to our users. > Distributed Cache gives inconsistent result if cache files get deleted from > task tracker > ----------------------------------------------------------------------------------------- > > Key: YARN-1036 > URL: https://issues.apache.org/jira/browse/YARN-1036 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 0.23.9 > Reporter: Ravi Prakash > Assignee: Ravi Prakash > Attachments: YARN-1036.branch-0.23.patch > > > This is a JIRA to backport MAPREDUCE-4342.
