Kai Zheng updated HDFS-7859:
----------------------------
Resolution: Fixed
Hadoop Flags: Incompatible change,Reviewed
Fix Version/s: 3.0.0-beta1
Status: Resolved (was: Patch Available)
Committed to trunk and branch 3.0. Thanks [~Sammi] for making the final patch,
[~eddyxu] for the review, and [~andrew.wang] for the driving!
This was a long time effort. Many thanks to [~xinwei] for the initial taking
and patch, [~szetszwo] for the guiding, [~zhz] and [~jingzhao] for the ideas.
With HDFS-12395 also in soon, I'm happy we can make it for the BETA 1 release,
as many people asked in the past like some requests we can see in HDFS-7337.

> 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.
