Sumit Singhal commented on LOG4J2-1482:
---------------------------------------
Yes I am talking about the empty line with commas, i.e., ",,".
This would come in every subsequent file. And this would affect the parsing of
the CSV file.
Below is the code snippet I am using.
Logger logger = LoggerFactory.getLogger("csvlogger");
logger.info("Info Message!", val1, val2, val3);
Here val1, val2, val3 would be the variables.
I hope this is what you were asking for.

> Improper header in CsvParameterLayout

> Key: LOG4J2-1482
> URL: https://issues.apache.org/jira/browse/LOG4J2-1482
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.6.2
> Reporter: Sumit Singhal
> Attachments: csv-with-line-seprator-1.csv,
> csv-with-line-seprator-2.csv, csv-without-line-separator-1.csv,
> csv-without-line-separator-2.csv

>
> The header and first record are coming in first line in case of
> CsvParameterLayout. This messes up the header for the first file as well as
> for the subsequent files. And if we use line separator as part of header, the
> first file seems ok but the first record in subsequent files comes out to be
> empty with only commas.
