> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Affects Versions: 0.9.0
> Environment: 64e3ec52b93e9331aa5179e040eca19afece8317 | DRILL-2611: value vectors should report valid value count | 16.04.2015 @ 13:53:34 EDT

> When column projected on left hand side of UNION ALL operator is non-existent (it does not exist in the parquet file) and column projected on RHS is of varchar type and it exists in the parquet file. In the UNION ALL results we see that the varchar data coming from RHS is lost and returned as null. Test was performed on 4 node cluster on CentOS. Data was read from two different parquet files.
