Eli Collins updated HDFS-4053:

Good catch Uma. We'll always use the default in hdfs-default.xml but we should update the define here as well so they're consistent.

> 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.
