> When the user needs to configure a larger split metainfo file size, mapred-default.xml
points to the mapreduce.job.split.metainfo.maxsize property.  However the ApplicationMaster
actually uses the mapreduce.*jobtracker*.split.metainfo.maxsize property when determining
the largest allowed size.  This leads to much confusion on the part of end-users trying to
increase the allowed limit.
