Wangda Tan commented on YARN-4225:
----------------------------------
Thanks [~eepayne],
bq. The use case is a newer client is querying an older server...
I'm wondering if this is a valid use case: IMHO, rolling upgrade should be
always server-first. If we plan support newer client talks to older server, we
may experience many issues AND we need to add this to Hadoop's code
compatibility policy.
