Kai Zheng commented on HDFS-7866:
---------------------------------
bq. The methods in INodeFileAttributes are all public so not sure why it's
complaining the public is redundant.
Methods defined in Java interface are public by default, that's why it
complains. I guess you can remove all the modifier to fix it.
bq. One way may be to make all the tests get the EC policy from
StripedFileTestUtil, which in turn picks a policy randomly from all system
policies. This can be done in a separate JIRA of course.
Sounds good to update tests separately. We may also need to consider this per
test: 1) the system default policy should be ensured to get tested in all
cases; 2) some tests may consider multiple policies co-existing or co-working
together.

> This is to extend NameNode to load, list and sync predefine EC schemas in
> authorized and controlled approach. The provided facilities will be used to
> implement DFSAdmin commands so admin can list available EC schemas, then
> could choose some of them for target EC zones.
