Sean Owen commented on SPARK-14103:
-----------------------------------

Did you compute the maximum line length? that's not quite what you show 
earlier, and not what you show in this snippet. Assuming you did, it still 
doesn't explain why the parser thinks there is a run of text far too long to 
process.  Your example does not exercise the CSV parser here. You should try 
raising the limit just to confirm it fixes it (and, then you have your 
workaround) and then do a little more debugging to understand why it's seeing a 
very long line.
