Subject [jira] [Created] (DRILL-2837) Resolve what JDBC's Statement.cancel() really does

Daniel Barclay (Drill) created DRILL-2837:

             Summary: Resolve what JDBC's Statement.cancel() really does
                 Key: DRILL-2837
                 URL: https://issues.apache.org/jira/browse/DRILL-2837
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
            Reporter: Daniel Barclay (Drill)
            Assignee: Daniel Barclay (Drill)

It is not clear exactly what JDBC's Statement.cancel() is supposed to do.

It seems reasonable to think that calling calling() on a Statement causes any associated query
that has not already completed to be canceled, causes any associated ResultSet that is not
already closed to be closed, and causes the statement to bebe closed.

The Javadoc method description for it says only:

"Cancels this Statement object if both the DBMS and driver support aborting an SQL statement.
This method can be used by one thread to cancel a statement that is being executed by another

It seems reasonable to think think that calling cancel() on a Statement causes the statement
to be closed

(In particular, it doesn't say whether the Statement object is closed, doesn't say wha
