[jira] [Updated] (DRILL-4519) File system directory-based partition
pruning doesn't work correctly with parquet metadata
[ https://issues.apache.org/jira/browse/DRILL-4519?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Miroslav Holubec updated DRILL-4519:
------------------------------------
Description:
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}
select dir0, dir1, dir2 from hdfs.test.indexed;
dir0 = HH, dir1 = null, dir2 = null, dir3 = null
{noformat}
