[jira] [Commented] (AVRO-982) NettyTransceiver: can hang on
connection interruption
[ https://issues.apache.org/jira/browse/AVRO-982?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13170626#comment-13170626 ]
Doug Cutting commented on AVRO-982:
-----------------------------------
It would be great to have a test that this fixes. I tried some simple changes to TestNettyServerWithCallbacks to reproduce the problem and could not. Can you devise a test?

> 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.
