------------------------------------

    Status: Open  (was: Patch Available)

bq. Jothi, is the -1 on javadoc expected ? 

Jothi - could this be due to the wrong import in o.a.h.mapreduce.OutputCommitter:

{noformat}
Index: src/java/org/apache/hadoop/mapreduce/OutputCommitter.java

> The OutputCommitter needs an abortJob method to clean up from failed jobs. Currently
there is no way to distinguish between failed or succeeded jobs, making it impossible to write
output promotion code.
