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

Thanks Sammi for the hard work and making it pretty easy to support test of new 
erasure coding policies.
+1 on the latest patch.

> Support an XOR policy XOR-2-1-64k in HDFS

> So far, "hdfs erasurecode" command supports three policies, 
> RS-DEFAULT-3-2-64k, RS-DEFAULT-6-3-64k and RS-LEGACY-6-3-64k. This task is 
> going to add XOR-2-1-64k policy to this command.
