Krystal created PHOENIX-970:
-------------------------------

             Summary: COUNT function against character column fails with "cast function for type BIT is not defined"
                 Key: PHOENIX-970
                 URL: https://issues.apache.org/jira/browse/PHOENIX-970
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 1.0
            Reporter: Krystal


The following query failed:
select count(distinct(name)) from voter;

Explicitly cast the "name" column to a varchar (select count(distinct(cast(name as varchar(25)))) from voter;) gave the same error.

Also, casting an integer column to a varchar with count resulted in the same error:
select count(cast(age as varchar(5))) from student;
Failure while running fragment. < RuntimeException:[ cast function for type BIT is not defined
