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

Thanks for the update, Eli.
+1, lgtm. MR configs can be looked at MR-97 JIRA as Arun reopened it.

> 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.
