Description

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?
