Harsh J commented on MAPREDUCE-4630:
------------------------------------
I agree with Alex.
I haven't seen much use-case for this (of overriding dfs.blocksize many times
in general), and besides, the config param is pretty well known so can be set
via -D opts or via Configuration.set(…)?
Are these options not sufficient Radim?
