---------------------------------------------
[~jdere] Can you add explain to your test? So that we see the UDF cast.
> Add unit test to test implicit conversion during dynamic

> This particular case was failing in Hive 0.13 because the string "key" column
> was not being converted to INT when written to the ORC file, resulting in a
> type cast error when reading data from the table.
> HIVE-8151 seems to have fixed this issue, but I would like to add a unit test
> to make sure we don't regress.
> {noformat}
> create table implicit_cast_during_insert (c1 int, c2 string)
> partitioned by (p1 string) stored as orc;
> set hive.exec.dynamic.partition.mode=nonstrict;
> insert overwrite table implicit_cast_during_insert partition (p1)
> select key, value, key key1 from (select * from src where key = 0) q
> distribute by key1 sort by key1;
> select * from implicit_cast_during_insert;
> drop table implicit_cast_during_insert;
