Jark Wu created FLINK-15223:
-------------------------------
Summary: Csv connector should unescape delimiter parameter
character
Key: FLINK-15223
URL: https://issues.apache.org/jira/browse/FLINK-15223
Project: Flink
Issue Type: Bug
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Reporter: Jark Wu
Fix For: 1.10.0
As described in documentation[1], a csv format can use
{{'format.line-delimiter' = '\n'}} to specify line delimiter. However, the
property value is parsed into two characters "\n" , this result to reading
failed. There is no workaround for now, unless fix it. The delimiter should be
unescaped, e.g. using {{StringEscapeUtils.unescapeJava}}. Note that both old
csv and new csv have the same problem, and both {{field-delimiter}} and
{{line-delimiter}}.
