Haohui Mai commented on HDFS-9055:
----------------------------------
bq. it does not work with curl or wget despite the above assurances.
This is a false statement. You're good as long as you're able to talk HTTP and
protobuf. There is no out-of-box support but it doesn't mean it's not feasible.
bq. it is HIGHLY HIGHLY HIGHLY recommend to use protobuf 3.x in order to get
the widest possible language coverage.
There is no need to use protobuf 3.x. The format is wire-compatible with
protobuf 2.x, which means the current RPC will work without changes.
bq. So yeah, gRPC is a total non-starter without massive delays and reworking
things like the entire RPC layer.
This looks highly speculative from both design and implementation point of
view. Have you tried it out?
