[jira] [Updated] (HADOOP-18360) Update commons-csv from 1.0 to 1.9.0.
[ https://issues.apache.org/jira/browse/HADOOP-18360?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
fanshilun updated HADOOP-18360:
-------------------------------
Description:
commons-csv 1.0 is a very old jar, mvnrepository shows this jar as the 2014 version, I have compiled and tested locally, I think this jar can be upgraded to commons-csv 1.9 version.
The link to the release note is as follows:
[https://commons.apache.org/proper/commons-csv/changes-report.html]
We can see that the new version fixes some issues.
I read the code used, we use header related methods. We found that many header-related methods have been upgraded.
*Release 1.1 – 2014-11-16*
CSVFormat#withHeader doesn't work well with #printComment, add withHeaderComments(String...).
CSVFormat.EXCEL should ignore empty header names.
*Release 1.2 – 2015-08-24*
CSVFormat.with* methods clear the header comments.
*Release 1.3 – 2016-05-09*
Add shortcut method for using first record as header to CSVFormat.
Add withHeader(Class<? extends Enum>) to CSVFormat.
CSVPrinter doesn't skip creation of header record if skipHeaderRecord is set to true.
Add IgnoreCase option for accessing header names.
*Release 1.5 – 2017-09-03*
Fix incorrect method name 'withFirstRowAsHeader' in user guide.
*Release 1.7 – 2019-06-01*
Cannot get headers in column order from CSVRecord.
*Release 1.8 – 2020-02-01*
CSVFormat#validate() does not account for allowDuplicateHeaderNames.
A single empty header is allowed when not allowing empty column headers.
*Release 1.9.0 – 2020-07-24*
Add possibility to use ResultSet header meta data as CSV header.
