> Project: Hadoop Common
> Issue Type: Sub-task
> Components: ipc

> Attachments: HADOOP-14034-branch-2.patch, HADOOP-14034-trunk.patch

>
> IPC layer exceptions generated in the readers are translated into fatal
> errors - resulting in connection closure. Ex. RetriableExceptions from call
> queue pushback.
> Always closing the connection degrades performance for all clients since a
> disconnected client will immediately reconnect on retry. Readers become
> overwhelmed servicing new connections and re-authentications from bad clients
> instead of servicing calls from good clients. The call queues run dry.
> Exceptions originating in the readers should be able to indicate if the
> exception is an error or fatal so connections can remain open.
