-----------------------------------
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
