Subject [jira] [Created] (DRILL-5145) Planner causes exception due to Drill CTAS Parquet file
Date Wed, 21 Dec 2016 07:30:58 GMT
Paul Rogers created DRILL-5145:
----------------------------------

             Summary: Planner causes exception due to Drill CTAS Parquet file
                 Key: DRILL-5145
                 URL: https://issues.apache.org/jira/browse/DRILL-5145
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.9.0
            Reporter: Paul Rogers


The {{TestWindowFrame}} unit test displays an (ignored) exception to the console about a bad
format in a Drill-created Parquet file. The query continues and the test succeeds, so the
exception must be ignored within the planner.

It is not entirely clear which specific test produces the error; it may be occurring when
the Drillbit is shutting down after the test completes.

Here I am assuming that the file comes from CTAS since no Parquet files appear to be included
in test resource; but this assessment is not certain.
