Review request for drill, Daniel Barclay, Hanifi Gunes, and Mehant Baid.


Repository: drill-git


Description
-------

Sqlline hangs when you try to cancel the query before the first result set has 
been returned.


Diffs
-----

  exec/jdbc/src/main/java/org/apache/drill/jdbc/DrillResultSet.java 88a6c6d 

Diff: https://reviews.apache.org/r/31419/diff/


Testing
-------

Tested with a query that takes a long time to return the first result set. 
Ctrl-C to exit the query. This fix simply addresses the hang. It does not fix 
Avatica to display cancellation in a nicer manner. Also, have not verified that 
the query cancellation occurs on the drillbit in all cases (waiting for 
DRILL-2245)


Thanks,

Parth Chandra
