---------------------------------------

bq. What do people think about changing this in branch-2? 
+1 for doing that. BTW please update the release note about the new behavior.

> 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.
