> In [DrillCursor|https://github.com/apache/drill/blob/master/exec/jdbc/src/main/java/org/apache/drill/jdbc/impl/DrillCursor.java#L199], consume all empty batches, not just non-continuous empty batches. This results in query cancellation (from sqlline) and incomplete results.
> Introduced (regression?) in DRILL-2548.
