Sergey Shelukhin created HIVE-4929:
--------------------------------------
Summary: the type of all numeric constants is changed to double in
the plan
Key: HIVE-4929
URL: https://issues.apache.org/jira/browse/HIVE-4929
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
There's code which, after the numeric type for a constant in where clause has
been chosen as the most restricted one or based on suffix, tries to change the
type to match the numeric column which the constant is being compared with.
However, due to a hack from HIVE-3059 every column type shows up as string in
that code, causing it to always change the constant type to double. This should
not be done (regardless of the hack).
Spinoff from HIVE-2702, large number of query outputs change so it will be a
big patch
