> 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.
