Description

Data types like TinyInt, SmallInt, BigInt or Decimal can be expressed as literals with postfix like Y, S, L, or BD appended to the number. These literals work in most Hive queries, but do not when they are used as partition column value. For a partitioned table like:
create table partcoltypenum (key int, value string) partitioned by (tint tinyint, sint smallint, bint bigint);
insert into partcoltypenum partition (tint=100Y, sint=10000S, bint=100000000000L) select key, value from src limit 30;

Queries like select, describe and drop partition do not work. For an example
select * from partcoltypenum where tint=100Y and sint=10000S and bint=100000000000L;
does not return any rows.
