dhruba borthakur updated HADOOP-1372:
-------------------------------------
Attachment: (was: localDirAllocator.patch)
> DFS Clients should start using the org.apache.hadoop.fs.LocalDirAllocator
> -------------------------------------------------------------------------
>
> Key: HADOOP-1372
> URL: https://issues.apache.org/jira/browse/HADOOP-1372
> Project: Hadoop
> Issue Type: Bug
> Components: dfs
> Reporter: Devaraj Das
> Assignee: dhruba borthakur
> Fix For: 0.14.0
>
> Attachments: localDirAllocator2.patch
>
>
> I encountered this exception during one of the randomwriter runs. I think
> this situation can be improved by using
> org.apache.hadoop.fs.LocalDirAllocator that has been written to handle these
> kind of problems. I set the fix version as 0.14 but wonder whether it makes
> sense to have it in 0.13 itself (since the amount of code change would not be
> much).
