Description

When a query is executed using beeline and the query is cancelled due to query timeout or kill query or triggers and when there is cursor on operation log row set, the cursor can thrown an exception as cancel will cleanup the operation log in the background. This can return a non-zero exit code in beeline. Query cancellation on success should return exit code 0.

Adding a delay to the cleanup of operation logging in operation cancel can avoid the close during read.
