Description

Impala JDBC driver 2.5.16

JDBC driver can't cancel query with predicate which include function.

For example:

select ClusterID, count(distinct userID)
from dwh.DimUser
where to_date(RegTime) = '2015-01-01'
group by ClusterID

When invoke driver's Statement.cancel() API Impala query still running.

But this query gets cancelled successfully:

select ClusterID, count(distinct userID)
from dwh.DimUser
where RegTime = '2015-01-01'
group by ClusterID
