Cancellation via shell may hang over SSL

    Details

      Description

      On an internal cluster with security enabled, it was reported that queries couldn't be cancelled via the shell. When the user tried to cancel the query via ctrl-C, the shell printed the warning:

      ^C Cancelling Query
      Failed to reconnect and close (try 1/3): TSocket read 0 bytes
       Cancelling Query
      Failed to reconnect and close (try 2/3): TSocket read 0 bytes
       Cancelling Query
      Failed to reconnect and close (try 3/3): TSocket read 0 bytes
      

      The shell did not return with a new prompt and the query was still active on the server until the query was manually cancelled via the web UI. At that point, the query was cancelled successfully, and the shell finally returned with the message:

      Application Exception : Default TException.
      

      This was using kerberos/ssl. It seemed to be reproducing regularly.
