--------------------------------------------
Status: Patch Available (was: Reopened)

> ---------------------------------------------------------------------
>
> Key: HADOOP-3041
> URL: https://issues.apache.org/jira/browse/HADOOP-3041
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.16.1
> Environment: all
> Reporter: Alejandro Abdelnur
> Assignee: Amareshwari Sriramadasu
> Priority: Blocker
> Fix For: 0.17.0
>
> Attachments: patch-3041-0.16.2.txt, patch-3041.txt, patch-3041.txt
>
>
> Until 0.16.0 the value of the getOutputPath() method, if queried within a
> task, pointed to the part file assigned to the task.
> For example: /user/foo/myoutput/part_00000
> In 0.16.1, now it returns an internal hadoop for the task output temporary
> location.
> For the above example: /user/foo/myoutput/_temporary/part_00000
> This change breaks applications that use the getOutputPath() to compute other
> directories.
> IMO, this has always being broken, Hadoop should not change the values of
> properties injected by the client, instead it should use private properties
> or internal helper methods.
