> Allow ipc layer exceptions to selectively close connections
> -----------------------------------------------------------
>
> Key: HADOOP-14034
> URL: https://issues.apache.org/jira/browse/HADOOP-14034
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: ipc
> Affects Versions: 2.7.0
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> 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.
