Lars George commented on HBASE-1385:
------------------------------------
Another comment, I think MAPREDUCE-287 is already halfway implemented as the
new Job class is lacking the option to set the number of Mappers. The described
option in FileInputFormat is also missing, so I removed the option too where
ever it applied.
> Revamp TableInputFormat, needs updating to match hadoop 0.20.x AND remove bit
> where we can make < maps than regions
