Luke Lu commented on HADOOP-9683:
---------------------------------
The current count is not very useful in the catch block. I was hoping that you
can propagate the count via your RpcReplyException. I'm fine with addressing it
in a separate jira (useful as a unique signature for debugging of alternative
client impls) though. +1 for the patch.
> Wrap IpcConnectionContext in RPC headers

> After HADOOP-9421, all RPC exchanges (including SASL) are wrapped in RPC
> headers except IpcConnectionContext, which is still raw protobuf, which makes
> request pipelining (a desirable feature for things like HDFS-2856) impossible
> to achieve in a backward compatible way. Let's finish the job and wrap
> IpcConnectionContext with the RPC request header with the call id of
> SET_IPC_CONNECTION_CONTEXT. Or simply make it an optional field in the RPC
> request header that gets set for the first RPC call of a given stream.
