Subject [jira] [Created] (AVRO-2047) NettyTransceiver can NPE when getRemoteName() is called
Date Fri, 14 Jul 2017 05:42:00 GMT
Clement Pang created AVRO-2047:
----------------------------------

             Summary: NettyTransceiver can NPE when getRemoteName() is called
                 Key: AVRO-2047
                 URL: https://issues.apache.org/jira/browse/AVRO-2047
             Project: Avro
          Issue Type: Bug
    Affects Versions: 1.7.7
            Reporter: Clement Pang


NettyTransceiver can NPE if the channel is closed while a request is underway. The correct
thing to do seems to be to check for null and throw an IOException ("underlying transport
no longer available").
