Luke Lu commented on HADOOP-9421:
---------------------------------
bq. When it gets an RPC error, such as invalid rpc version or unsupported
serialization, it blows up trying to decode it as SASL.
The server should reply with client version appropriate response, see
Server#setupBadVersionResponse, which currently doesn't handle sasl correctly
for >=9 case, because the code not finished yet :). But this is a separate
issue. Stuffing SASL exchange in RpcRequestHeaderProto seems to be hack to me
to avoid fixing the bad version response.
> Convert SASL to use ProtoBuf and add lengths for non-blocking processing
