Kai Zheng commented on HDFS-7859:
---------------------------------
bq.What do you mean? Could you give an example?
Well, my last said was bad and inaccurate. After double checking related codes,
I saw only stripped blocks derived from the following hard-coded values are
persisted in the image. So please ignore the saying.
bq.What are the subsequent issues?
We do have some and will sort them out later. I have opened HDFS-8156 to
resolve some deps caused by HDFS-7866, originally planned to be done here.

> persist EC schemas in NameNode centrally and reliably, so that EC zones can
> reference them by name efficiently.
