Kai Zheng commented on HDFS-11172:
----------------------------------

It's good to support an RS(10, 4) policy, as it's widely used in the industry. Thanks [~zhouwei]
for doing this.

> 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 RS-DEFAULT-10-4-64k policy to this command.
