> A variation of alter_partition_change_col.q produces wrong result:
> {code}
> SET hive.exec.dynamic.partition.mode = nonstrict;
> create table alter_partition_change_col0 (c1 string, c2 string);
> load data local inpath 'dec.txt' overwrite into table alter_partition_change_col0;
> create table alter_partition_change_col1 (c1 string, c2 string) partitioned by (p1 string
comment 'Column p1', p2 string comment 'Column p2');
> insert overwrite table alter_partition_change_col1 partition (p1, p2)
>   select c1, c2, 'abc', '123' from alter_partition_change_col0
>   union all
>   select c1, c2, cast(null as string), '123' from alter_partition_change_col0;
> select * from alter_partition_change_col1 where p1='__HIVE_DEFAULT_PARTITION__' or lower(p1)='a';
> {code}
> The "select" statement does not produce the rows containing "__HIVE_DEFAULT_PARTITION__".
> We need another condition containing a udf so the condition is not recognized by PartFilterExprUtil.makeExpressionTree
in ObjectStore. Looks like HIVE-11208 breaks it.
