--------------------------------

             Summary: Improve logging in AbstractServerHandler#channelRead(ChannelHandlerContext, Object)
                 Key: FLINK-17501
                 URL: https://issues.apache.org/jira/browse/FLINK-17501
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Queryable State
            Reporter: Gary Yao
            Assignee: Gary Yao
             Fix For: 1.11.0


Improve logging in {{AbstractServerHandler#channelRead(ChannelHandlerContext, Object)}}. If an Error is thrown, it should be logged as early as possible. Currently we try to serialize and send an error response to the client before logging the error; this can fail and mask the original exception.
