Date Mon, 15 Oct 2012 19:08:03 GMT

Harsh J commented on HDFS-4053:
-------------------------------

+1 on the change personally, I've not seen more than a few instances of 64 MB in use among
configs I go through, among the several clusters I help out on.

> 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.
