[jira] [Updated] (PIG-3141) Giving CSVExcelStorage an option to handle header rows

["Jonathan Packer (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-3141?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Packer updated PIG-3141:
---------------------------------

    Attachment: csv_updated.patch

Re-adds the choice of delimiter, and makes the "header treatment" argument the last one to maintain backwards compatibility. All unit-tests from the old CSVExcelStorage pass.

> Adds an argument to CSVExcelStorage to skip the header row when loading. This works properly with multiple small files each with a header being combined into one split, or a large file with a single header being split into multiple splits.
> Also fixes a few bugs with CSVExcelStorage, including PIG-2470 and a bug involving quoted fields at the end of a line not escaping properly.
> Removes the choice of delimiter, since a CSV file ought to only use a comma delimiter, hence the name.
