Description

https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/shufflehandler/ShuffleHandler.java#L616

 

For corner case debugging, it would be helpful to understand when netty processed OPEN/BOUND/CLOSE/RECEIVED/CONNECTED events along with payload details.

Adding "LoggingHandler" in ChannelPipeline mode can help in debugging.
