Date Tue, 23 Feb 2016 18:35:18 GMT
Deneche A. Hakim created DRILL-4427:
---------------------------------------

             Summary: Table not found when querying a parquet table with metadata cache
                 Key: DRILL-4427
                 URL: https://issues.apache.org/jira/browse/DRILL-4427
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.5.0
            Reporter: Deneche A. Hakim
             Fix For: 1.6.0


The following query runs fine without metadata cache but fails when metadata cache is available:
{noformat}
0: jdbc:drill:zk=local> select count(*) from `tpch10/lineitem/*`;
+-----------+
|  EXPR$0   |
+-----------+
| 59986052  |
+-----------+
1 row selected (0.148 seconds)
0: jdbc:drill:zk=local> refresh table metadata `tpch10/lineitem`;
+-------+-----------------------------------------------------------+
|  ok   |                          summary                          |
+-------+-----------------------------------------------------------+
| true  | Successfully updated metadata for table tpch10/lineitem.  |
+-------+-----------------------------------------------------------+
1 row selected (0.182 seconds)
0: jdbc:drill:zk=local> select count(*) from `tpch10/lineitem/*`;

SEVERE: org.apache.calcite.runtime.CalciteContextException: From line 1, column 22 to line
1, column 40: Table 'tpch10/lineitem/*' not found
Error: VALIDATION ERROR: From line 1, column 22 to line 1, column 40: Table 'tpch10/lineitem/*'
not found
{noformat}

Initial investigation shows that FileSelection.create(DrillFileSystem, String, String) calls
fs.globStatus() without passing a DrillPathFilter which will return the metadata cache file
on top of the selection.
