Parth Chandra commented on DRILL-1498:
--------------------------------------
I'm not sure if the server ever sends the client a bogus or spurious message.
This might be a problem in reading the data sent back by the server. (I've
tried to reproduce this using the C++ client QuerySubmitter and have so far not
succeeded).
I would like a reproduction of this problem before trying to fix it. Some
things I would look at:
1) Is this specific to a platform? Win32 perhaps?
2) Is there a corresponding log on the drillbit that shows us a spurious
message being sent? If so, we need to fix this in the drillbit.
Also, DRILL-1305 should handle all 'bad messages' coming in, perhaps?
> Drill Client to handle handshake messages in handleRead and to ignore

> Occasionally the client will receive handshake messages from the server.
> Requests should be reponded to and responses should be ignored. Spurious
> Query_Handle and Query_Result messages (where coordination id and query id =
> 0, respectively) should also be ignored.
