             Summary: Make all the "Connection reset by peer" exception wrapped as RemoteTransportException
                 Key: FLINK-21952
                 URL: https://issues.apache.org/jira/browse/FLINK-21952
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Network
            Reporter: Yun Gao


In CreditBasedPartitionRequestClientHandler#exceptionCaught, the IOException or the exception with exact message "Connection reset by peer" are marked as RemoteTransportException. 

However, with the current Netty implementation, sometimes it might throw 
{code:java}
org.apache.flink.shaded.netty4.io.netty.channel.unix.Errors$NativeIoException: readAddress(..) failed: Connection reset by peer
{code}
in some case. It would be also wrapped as LocalTransportException, which might cause some confusion.
