Subject [jira] [Created] (DRILL-2804) IOB Exception : Project non-existent column from compressed CSV file (.tgz)
Date Thu, 16 Apr 2015 15:31:00 GMT
Khurram Faraaz created DRILL-2804:
-------------------------------------

             Summary: IOB Exception : Project non-existent column from compressed CSV file
(.tgz)
                 Key: DRILL-2804
                 URL: https://issues.apache.org/jira/browse/DRILL-2804
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Text & CSV
    Affects Versions: 0.9.0
         Environment: 9d92b8e319f2d46e8659d903d355450e15946533 | DRILL-2580: Exit early from
HashJoinBatch if build side is empty | 26.03.2015 @ 16:13:53 EDT
            Reporter: Khurram Faraaz
            Assignee: Steven Phillips


Query that projects a non-existent column from a CSV file that has an extension, (.tgz) results
in IOB Exception. Whereas, the same query that projects a non-existent column (columns[8])
in the test query, does not return the exception, and we see the expected results where null
is returned for a non-existent column in a CSV file that is NOT compressed in (.tgz) compression
format. Tests were performed on 4 node cluster on CentOS.
