> When filtering Parquet tables using a partition column, the query fails saying the column
does not exist:
> {noformat}
> hive> create table part1 (id int, content string) partitioned by (p string) stored
as parquet;
> hive> alter table part1 add partition (p='p1');
> hive> insert into table part1 partition (p='p1') values (1, 'a'), (2, 'b');
> hive> select id from part1 where p='p1';
> Failed with exception java.io.IOException:java.lang.IllegalArgumentException: Column
[p] was not found in schema!
> Time taken: 0.151 seconds
> {noformat}
> It is correct that the partition column is not part of the Parquet schema. So, the fix
should be to remove such expression from the Parquet PPD.
