Subject [jira] [Created] (HIVE-8615) beeline csv,tsv outputformat needs backward compatibility mode

Thejas M Nair created HIVE-8615:
-----------------------------------

             Summary: beeline csv,tsv outputformat needs backward compatibility mode
                 Key: HIVE-8615
                 URL: https://issues.apache.org/jira/browse/HIVE-8615
             Project: Hive
          Issue Type: Bug
          Components: Beeline
    Affects Versions: 0.14.0
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair
            Priority: Critical
             Fix For: 0.14.0


Changes in HIVE-7390 break backward compatibility for beeline csv and tsv formats.
This can cause problems for users upgrading to hive 0.14, if they have code for parsing the
old output format. Instead of removing the old format in this release, we should consider
it deprecated and support it in a few releases before removing it completely.

Incompatible Changes in the tsv and csv formats-
- Old format quoted every field. New format quotes only fields that contain a delimiter or
the quoteing char.
- Old format quoted using single quotes, new format quotes using double quotes
- Old format didn't escape quotes in a field (a bug). New format does escape the quotes
