------------------------------------
Summary: 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
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.
