Xinwei Qin commented on HDFS-7859:
-----------------------------------
[~rakeshr] [~drankye], and [~zhz], thanks for your comments and clarifications.
Now, it is a good time to update this patch, though we should have a more clear
about the details of custom policies. I am glad to rebase the patch with latest
code and maybe attach it tomorrow.

> In meetup discussion with [~zhz] and [~jingzhao], it's suggested that we
> persist EC schemas in NameNode centrally and reliably, so that EC zones can
> reference them by name efficiently.
