Subject [jira] [Commented] (HDFS-7859) Erasure Coding: Persist EC schemas in NameNode
Date Tue, 05 May 2015 23:41:01 GMT

Kai Zheng commented on HDFS-7859:
---------------------------------

Nicholas,

This was already move out of HDFS-7285 you did and there was no plan to commit this in phase
I AFAIK. I thought the patch updated here is good to have to be ready for follow-on once we
get the merge done.

> 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.
