Kai Zheng commented on HDFS-8062:
---------------------------------
Right now, for client to write and read, is it possible to use schema object
passed from NameNode, and we limit the use of the system default one only in
NameNode side? If not easy, we could get it done separately.
> Remove hard-coded values in favor of EC schema

> HDFS-7859 is to change fsimage and editlog in NameNode to persist EC schemas;
> HDFS-7866 is to manage EC schemas in NameNode, loading, syncing between
> persisted ones in image and predefined ones in XML.
> This is to revisit all the places in NameNode that uses hard-coded values in
> favor of {{ECSchema}}.
