Vinod Kumar Vavilapalli resolved MAPREDUCE-2049.
------------------------------------------------
Resolution: Won't Fix
We haven't done a 1.x/0.21/0.22 based release in a long long time. Unlikely
this issue is going to be fixed/released.
This should happen in 2.x at all, but if if you see something, please file a
new ticket.
Closing this as Won't Fix. Please revert back if you disagree. Thanks.
> JT and TT should prune invalid local dirs on startup
> ----------------------------------------------------

> Key: MAPREDUCE-2049
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2049
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker, tasktracker
> Affects Versions: 0.21.0, 0.22.0
> Reporter: Eli Collins
> Assignee: Zheng Shao
> Priority: Minor
>
> MRAsyncDiskService fails when it's given local dirs it can't create or write.
> Per MAPREDUCE-1213 this conflicts with the previous behavior. The TTs will no
> longer start on hosts where the config has localdirs that can not be created
> (ie if some hosts don't have the same local mounts).
> The TT and JT should prune out invalid local dirs (ones that fail
> checkLocalDirs ie that it can not create) before giving them to
> MRAsyncDiskService and using them otherwise.
> Also mapred-default.xml states that mapred.local.dir that do not exist are
> ignored, this should be updated as directories that don't exist are created
> (if possible), they're only ignored if they can not be created.
