                 URL: https://issues.apache.org/jira/browse/HIVE-3108

Suppose "stocks" is a managed OR external table, partitioned by "exchange" and "symbol". "count(DISTINCT
x)" returns 0 for either "exchange", "symbol", or both:

hive> SELECT count(DISTINCT exchange), count(DISTINCT symbol) from stocks;
0  0
