Sergio Peña commented on HIVE-14251:
I'm moving this JIRA out of 2.1.1 release as it is not a blocker nor critical
for a 2.1.1 RC version. Feel free to commit it to branch 2.1 if the patch is
ready before the release.

Yes. It should affect all of them. I will backport to those branches.

Does this affect branch-1? Having incorrect results should warrant a fix in all
the branches (2.1, 2.0, 1.3?)

Doc note: [~aihuaxu] documented this in the Union wikidoc.
* [Union -- Column Type Conversion |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Union#LanguageManualUnion-ColumnTypeConversion]
Question: Should this also be mentioned in the section on implicit conversions
in the Data types doc?

[~ctang.ma], [~mohitsabharwal] and [~ashutoshc] Can you take another look at
the patch? Tried to follow what Postgres and Oracle do and we will now force to
use cast if the types are not in the same type group.

I have found Postgres & Oracle to be lot more closer to standard then mysql, so
yes I would follow their behavior. If that implies throwing exception here,
that would be right course of action.
Current behavior is erroneous we need not to be backward compatible with our
erroneous behavior : )

[~ashutoshc] Do you have any opinion which approach we should go forward? Seems
hive follows more Postgres. Should we throw exception for such case as Postgres
and Oracle do? Of course, it will have compatibility issue and will affect some
existing usages.

Thanks for the suggestion. I went through the sql standard. Seems like the
standard is treating union as another union join, but doesn't explicitly
mention the behavior of mismatched type. Oracle requires the union types are in
the same type group from the doc (I don't have one either to try out either),
but the doc is pretty clear that it won't do implicit type conversion across
type groups
(https://docs.oracle.com/cd/B19306_01/server.102/b14200/queries004.htm).

When we are making such semantic changes we should make change which takes us
closer to standard. So, it should help to read that to see what standard has to
say here.
I took this query and ran it against few databases:
* MySQL : same result as you are trying to achieve
* Postgres : exception : ERROR: UNION types date and integer cannot be matched
Position: 53
* SQLServer: Different result set. It figured common type as date 2016-01-01
00:00:00.000 1900-01-06 00:00:00.000 1900-01-02 06:00:00.000
Couldn't try on oracle as I didnt had it handy. That would be good experiment
too.
Clearly its not consistent. My suggestion would be to read standard and try to
emulate that as much as possible.

Yeah. Actually implicitConvertible() is not completely accurate I feel. I just
put the comment why I try to avoid reusing the same function.
So for comparison of string and double, then we should compare them in double
type. That's implicitConvertible() is trying to do, returning true for string
=> double conversion.
I feel comparison and union do need separate functions though.

Aihua Xu commented on HIVE-14251:
-
Thanks for reviewing.
Originally I thought of reusing, but later I decided not to and gave a new name
to completely differentiate from implicitConvertible().
implicitConvertible() is used in the data comparison and isCommonTypeOf() is
used in union all operator. In fact, they could have different behaviors, I
guess, not only for string and double, but for any types from different groups,
seems they may or may have opposite result. e.g., for void and string, I'm not
sure what should return for comparison; but for union, seems reasonable to
return string. If it's numeric types, like int, double, then both should return
double.
Right now I only changed the union behavior of string and double and haven't
touched the others. I feel we need to evaluate them as well but I will defer
when we have the complains.

Chaoyu Tang commented on HIVE-14251:
[~aihuaxu] Do you know why and under what situation the string could be
considered to be implicitly converted to double? I believe it breaks your case
because the date string could be converted to double. If we add a flag to
disable this implicit conversion generally in getCommonClassForUnionAll, will
it bring in possible backward type incompatibility in some queries with union
all for type string and double?

Mohit Sabharwal commented on HIVE-14251:
LGTM.
If i understand correctly, the only difference between isCommonTypeOf and
implicitConvertible is this line
{code}
// Allow implicit String to Double conversion
if (fromPg == PrimitiveGrouping.STRING_GROUP && to ==
PrimitiveCategory.DOUBLE) {
return true;
}
{code}
Wondering if it's easy to re-use implicitConvertible instead of duplicating the
code ? Maybe add a flag to the method
for String to Double conversion ?
