--------------------------------------------------------------
After a lot of investigation into these two errors, they seem to be slightly
related.
The TL;DR is that I think there is a bug in the class {{ReduceSinkOperator}},
but I am not 100% sure.
I started debugging Exception 1 first. It seems that
{{GenericUDFOPEqualOrGreaterThan}} tries to compare a {{Text}} object with
value {{value_1_3}} to a {{DateWritable}} object with value {{2015-06-22}}.
This happens inside the reduce method, and causes the code to throw a
{{ClassCastException}} and fail.
I compared the query plans for Query 1 vs. Query 3 (the output of {{EXPLAIN
...}}). Both plans require a single Map-Reduce job. The major difference is
that the Query 3 runs a Filter Operator in both the Map Task and the Reduce
Task, while Query 1 only runs a Filter Operator in the Map Task. I suspect the
Filter Operator in the Reduce Task of Query 3 is having some type of issue.
Here is the output of the {{EXPLAIN}} query:

{code}
The {{ReduceSinkOperator}} class is emitting the record:
*Record 1:*
{code}
{"key":{"_col0":"value_1_1","_col1":"value_1_2","_col2":{0:{"_col0":"value_1_3"}}},"value":null}
{code}
Which does not contain the {{date_column}} column, causing the
{{FilterOperator}} in the {{ExecReducer}} to fail.
Once I determined that {{ReduceSinkOperator}} is emitting this record, I did my
best to trace through the logic of {{ReduceSinkOperator}} to figure out why it
is emitting Record 1. The {{ReduceSinkOperator}} seems to emit a single record
for each {{DISTINCT}} keyword in the query, but the record will only have a
subset of its original columns. For each {{DISTINCT}} clause it will emit the
columns in the {{DISTINCT}} clause itself, as well as the columns in the
{{GROUP BY}}. For example, for {{COUNT(DISTINCT column_3)}} it will emit
{{column_1}}, {{column_2}}, and {{column_3}}, but not the {{date_column}}. *I'm
not sure the {{ReduceSinkOperator}} takes into account the situation where a
{{FilterOperator}} can occur on the reduce-side of a Hive query, over a column
not in the {{DISTINCT}} or {{GROUP BY}} clause.*
Exception 2 seems to be related to Exception 1. Exception 2 is thrown in the
class {{OpProcFactory.ReduceSinkLineage.process(...)}} method. This method does
some type of processing on the {{ReduceSinkOperator}} class (the same class
mentioned above when analyzing Exception 1), so my guess is that they are
related.
