Kay Kay updated MAPREDUCE-1334:
-------------------------------
Status: Open (was: Patch Available)
> contrib/index - test - TestIndexUpdater fails due to an additional presence
> of file _SUCCESS in hdfs
> -----------------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-1334
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1334
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/index
> Reporter: Kay Kay
> Priority: Critical
> Fix For: 0.21.0
>
> Attachments: MAPREDUCE-1334.patch
>
>
> $ cd src/contrib/index
> $ ant clean test
> This fails the test TestIndexUpdater due to a mismatch in the - doneFileNames
> - data structure, when it is being run with different parameters.
> (ArrayIndexOutOfBoundsException raised when inserting elements in
> doneFileNames, array ).
> Debugging further - there seems to be an additional file called as -
> hdfs://localhost:36021/myoutput/_SUCCESS , taken into consideration in
> addition to those that begins with done* . The presence of the extra file
> causes the error.
> Attaching a patch that would circumvent this by increasing the array length
> of shards by 1 .
> But longer term the test fixtures need to be probably revisited to see if the
> presence of _SUCCESS as a file is a good thing to begin with before we even
> get to this test case.
> Any comments / suggestions on the same welcome.
