Arun C Murthy commented on HDFS-4053:
-------------------------------------

You'd also have to bump up MR configs to be consistent: I've reopened MAPREDUCE-97.

> The default HDFS block size ({{dfs.blocksize}}) has been 64mb forever. 128mb works well
in practice on today's hardware configurations, most clusters I work with use it or higher
(eg 256mb). Let's bump to 128mb in trunk for v3.
