             Summary: Increase default value for maxCharsPerColumn
                 Key: SPARK-14260
                 URL: https://issues.apache.org/jira/browse/SPARK-14260
             Project: Spark
          Issue Type: Sub-task
            Reporter: Hyukjin Kwon
            Priority: Trivial


I guess the default value of the option {{maxCharsPerColumn}} looks relatively small,1000000 characters meaning 976KB.

It looks some of guys have a problem with this ending up setting the value manually.

According to [univocity API|http://docs.univocity.com/parsers/2.0.0/com/univocity/parsers/common/CommonSettings.html#setMaxCharsPerColumn(int)], this exists to avoid {{OutOfMemoryErrors}}.

If this does not harm performance, then I think it would be better to make the default value much bigger (eg. 10MB or 100MB) so that users do not take care of the lengths of each field in CSV file.

Apparently Apache CSV Parser does not have such limits.
