Zheng Shao commented on HIVE-1124:
----------------------------------
Patch line 993:
{code}
- ColumnInfo paraExprInfo = groupByInputRowResolver.get("", text);
+ ColumnInfo paraExprInfo = groupByInputRowResolver.get("",
entry.getKey());
{code}
Shall we use getExpression?
Otherwise it looks good.
> create view should expand the query text consistently

> We should expand the omitted alias in the same way in "select" and in "group

> Hive "Group By" recognize "group by" expressions by comparing the literal
> string.
