Mahadev konar updated HADOOP-3560:
----------------------------------

    Attachment: hadoop-3560_1.patch

this patch fixes the splits created in archive map reduce jobs so that splits 
are evenly distributed amongst the maps. The sync marker made the splits to be 
non uniform amongst the maps. The sync marker is called on each record append 
in the filesplits file.

> Archvies sometimes create empty part files.
