Description

In the Druid adapter, a query of "select" query type gives ClassCastException. This does not apply to other query types, such as "groupBy", so only SQL queries that have no aggregation (GROUP BY, HAVING) are affected.

The cause is that the DRUID_FETCH property recently changed from STRING to NUMBER but we are still accessing it using getString().
