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

Thanks [~andrew.wang] for the updates. +1 latest patch looks good to me.

> As discussed on HDFS-7859, the system default EC policy is mostly a relic from development
when the system only supported a single global policy. Now, we support multiple policies,
and the system default policy is mostly used by tests.
> We should refactor to remove this concept.
