Hello [~andrew.wang] [~drankye] [~xinwei] [~zhz]
Appreciate your work in this big patch which I quickly skimmed through it.
Now that a new fsimage section is added, we should also add support for OIV
XML/ReverseXML. And add OEV XML output for edits. How about we file follow-up
jiras for them? They are not as high priority as this patch itself.

> 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.
