> If the partition column 'dir0' is CAST inside a view and the query has a filter on that
column, then partition pruning interpreter evaluator encounters an AssertionError. 
> Table data in the example below is from test/resources/multilevel/parquet.  
> {code}
> create view dfs.tmp.myview2 as select cast(dir0 as varchar(100)) as myyear, dir1 as myquarter,
o_totalprice from `multilevel/parquet` ;
> select * from dfs.tmp.myview2 where myyear = '1995' and myquarter = 'Q2' and o_totalprice
< 40000.0;
> {code}
> Failure stack trace: 
> {code}
> Caused by: java.lang.AssertionError: Internal error: Error while applying rule PruneScanRule:Filter_On_Project,
> ...
> <skip>
> Caused by: java.lang.AssertionError: null
