Vinod Kumar Vavilapalli commented on MAPREDUCE-4630:
----------------------------------------------------
I agree with others here. What is the use-case? Are dfs.block.size and
mapreduce.input.fileinputformat.split.minsize not enough? Seems like you are
looking for {{void setMinInputSplitSize(Job job, long size)}} ?
> API for setting dfs.block.size
