---------------------------------------
Summary: Exception during partition pruning
Key: DRILL-3847
URL: https://issues.apache.org/jira/browse/DRILL-3847
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 1.2.0
Reporter: Victoria Markman
* This is happening when I run query below on a table partitioned by cd_demo_sk
which resulted in ~1.9 million files in the single directory.
* Metadata file is present customer_demographics_part_1
* If cast to varchar is replaced with the star in projection list: query works
* If cast to varchar replaced with integer columns: query works
* Same query runs to completion on the original table.
{code}
select
cast(cd_gender as varchar(10)),
cast(cd_credit_rating as varchar(10)),
cast(cd_marital_status as varchar(10)),
cd_dep_count
from
customer_demographics_part_1
where cd_demo_sk = 10000;
