> 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
> Fix For: 1.2.0
>
>
> 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
