---------------------------------------
Summary: CSV Writer should escape 'escapechar' when it exists in
the data
Key: SPARK-29437
URL: https://issues.apache.org/jira/browse/SPARK-29437
Project: Spark
Issue Type: Bug
Components: Input/Output
Affects Versions: 2.4.3
Reporter: Tomasz Bartczak
When the data contains escape character (default '\') it should either be
escaped or quoted.
Steps to reproduce:
[https://gist.github.com/kretes/58f7f66a0780681a44c175a2ac3c0da2]
The effect can be either bad data read or sometimes even unable to properly
read the csv, e.g. when escape character is the last character in the column -
it break the column reading for that row and effectively break e.g. type
inference for a dataframe
