-----------------------------------------
some updates about the jira.
The root cause of the problem is because the difference of sub-query {{select
ds as ds, ds as `date` from srcpart group by ds}} between tez and spark mode.

The Group By Operator appears in Map and Reducer in tez or spark mode. But the
keys of GroupByOperator in Reducer is different. In tez, the key is {{keys:
KEY._col0 (type: string)}} while in spark the key is {{keys: '2008-04-08'
(type: string)}}. This difference causes
[VectorizationContext#getVectorExpression|https://github.com/kellyzly/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/vector/VectorizationContext.java#L597
] returns
[getColumnVectorExpression|https://github.com/kellyzly/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/vector/VectorizationContext.java#L582]
in tez mode while returns
[getConstantVectorExpression|https://github.com/kellyzly/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/vector/VectorizationContext.java#L660].
