Subject [jira] [Created] (DRILL-4519) File system directory-based partition pruning doesn't work correctly with parquet metadata
Date Fri, 18 Mar 2016 15:16:33 GMT
Miroslav Holubec created DRILL-4519:
---------------------------------------

             Summary: File system directory-based partition pruning doesn't work correctly
with parquet metadata
                 Key: DRILL-4519
                 URL: https://issues.apache.org/jira/browse/DRILL-4519
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.5.0, 1.4.0
            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 querying root folder, dir0 contains HH folder name instead yearly
folder name. dir1...4 are null.
{noformat}
select dir0, dir1, dir2 from hdfs.test.indexed;
dir0 = HH,  dir1 = null, dir2 = null, dir3 = null
{noformat}
