Ashutosh Chauhan commented on HIVE-19604:
-----------------------------------------
Do we need instanceof check? These are results returned from Druid and they
will always be int. I think its safe to assume type is int since its unlikely
that Druid will change that.
> Incorrect Handling of Boolean in DruidSerde

> Results of boolean expressions from Druid are expressed in the form of
> numeric 1 or 0.
> When reading the results in DruidSerde both 1 and 0 are translated to String
> and then we call Boolean.valueOf(stringForm), this leads to the boolean being
> read always as false.
