[jira] [Created] (SPARK-25086) Incorrect Default Value For "escape"
For CSV Files
David Wilcox created SPARK-25086:
------------------------------------
Summary: Incorrect Default Value For "escape" For CSV Files
Key: SPARK-25086
URL: https://issues.apache.org/jira/browse/SPARK-25086
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.3.1
Reporter: David Wilcox
The RFC for CSV files ([https://tools.ietf.org/html/rfc4180]) indicates that the way that a double-quote is escaped is by preceding it with another double-quote:
{code:java}
7. If double-quotes are used to enclose fields, then a double-quote appearing inside a field must be escaped by preceding it with another double quote. For example: "aaa","b""bb","ccc"{code}
Your default value for "escape" violates the RFC. I think that we should fix the default value to be {{"}}, and those that want {{\}} to escape can override for non-RFC-conforming CSV files.
