> Key: DRILL-4519
> URL: https://issues.apache.org/jira/browse/DRILL-4519
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.4.0, 1.5.0, 1.6.0
> Reporter: Miroslav Holubec
>
> We have parquet files in folders with following convention YYYY/MM/DD/HH.
> Without drill's parquet metadata directory prunning works seamlessly.
> {noformat}
> select dir0, dir1, dir2 from hdfs.test.indexed;
> dir0 = YYYY, dir1 = MM, dir2 = DD, dir3 = HH
> {noformat}
> After creating metadata and executing same query, dir0 contains HH folder
> name instead yearly folder name. dir1...3 are null.
> {noformat}
> refresh table metadata hdfs.test.indexed;
> select dir0, dir1, dir2 from hdfs.test.indexed;
> dir0 = HH, dir1 = null, dir2 = null, dir3 = null
> {noformat}
