---------------------------------

             Summary: CASTing the column 'dir0' in view causes partition pruning to fail 
                 Key: DRILL-2852
                 URL: https://issues.apache.org/jira/browse/DRILL-2852
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 0.8.0
            Reporter: Aman Sinha
            Assignee: Aman Sinha


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
