Ravi Gummadi updated HADOOP-5895:
---------------------------------
Attachment: HADOOP-5895.patch
In computeBytesInMerges, getPassFactor() can return factor < number of segments
and even though n++ is done based on condition includeFinalMerge, that is not
good enough for the while loop to be executed.
Attaching patch with the fix. Please review and provide your comments.
> Log message shows -ve number of bytes to be merged in the final merge pass
> when there are no intermediate merges and merge factor is < number of segments
