[jira] [Commented] (SPARK-19834) csv escape of quote escape

["Hyukjin Kwon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-19834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15925375#comment-15925375 ] 

Hyukjin Kwon commented on SPARK-19834:
--------------------------------------

Just for other guys to easily track this, I guess this is a good to do as it is also described in univocity's README.md - https://github.com/uniVocity/univocity-parsers/blob/master/README.md#escaping-quote-escape-characters

However, there is a small bug in this option which was fixed in 2.4.0. So, I suggested to close this for now and bring it back when we bump up the library into 2.4.0 later.
Please refer the details in the PR.

Please let me know if anyone thinks differently.
