Subject [jira] [Created] (DRILL-4845) Malformed CSV throws IllegalArgumentException
Date Sat, 13 Aug 2016 01:07:20 GMT
Matt Keranen created DRILL-4845:

             Summary: Malformed CSV throws IllegalArgumentException
                 Key: DRILL-4845
                 URL: https://issues.apache.org/jira/browse/DRILL-4845
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Text & CSV
    Affects Versions: 1.6.0, 1.7.0
         Environment: CentOS 7
            Reporter: Matt Keranen

When reading CSV data, if lines are malformed, often an error such as the following is reported:

    Error: SYSTEM ERROR: IllegalArgumentException: length: -15150 (expected: >= 0)

Neither the error message reported to the client (with verbose errors on), nor on the drillbit
describe what or where the problem is.

Perhaps the CSV parser can throw exceptions that would help in locating what in the source
data is not parsing?
