Hi Anurag,

The easiest option would be , in your map reduce job set the dfs.block.size to 128 mb

Hi,
We have a situation where all files that we have are 64 MB block size.
I want to change these files (output of a map job mainly) to 128 MB blocks.

What would be good way to do this migration from 64 mb to 128 mb block
files ?

Thanks,
Anurag Tangri
