Edward Capriolo commented on HIVE-5137:
---------------------------------------
HiveInterface.fetchAll(). I know we have scripts that call FetchAll() or
fetchOne() on queries that probably do not have one. I wanted to make sure this
will not be a breaking change to existing code.
> A Hive SQL query should not return a ResultSet when the underlying plan does
> not include a FetchTask

> Currently, a query like "create table if not exists t2 as select * from t1"
> sets the hasResultSet to true in SQLOperation and in turn, the query returns
> a result set. However, as a DDL command, this should ideally not return a
> result set.
