-----------------------------------
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?
