NettyTransceiver: can hang on connection interruption
-----------------------------------------------------
Key: AVRO-982
URL: https://issues.apache.org/jira/browse/AVRO-982
Project: Avro
Issue Type: Improvement
Components: java
Reporter: Bruno Dumon
Priority: Minor
When stopping my avro server, I noticed that my avro client was hanging. This
makes it impossible for my client to retry the operation, as it hangs inside
the avro code:

In a similar situation elsewhere in the NettyTransceiver (method
exceptionCaught), the pending requests are canceled. It seems appropriate to do
that also on closed connections. I'll attach a patch.
