[jira] [Commented] (HIVE-6002) Create new ORC write version to address the changes to RLEv2

    [ https://issues.apache.org/jira/browse/HIVE-6002?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13845998#comment-13845998 ] 

Prasanth J commented on HIVE-6002:
----------------------------------

Do we need to discard "0.12" version completely? "0.12" version is not valid anymore. But config option still allows users to specify "0.12" version. In which case, should can we forcefully bump version to "0.12.1"?

> HIVE-5994 encodes large negative big integers wrongly. This results in loss of original data that is being written using orc write version 0.12. Bump up the version number to differentiate the bad writes by 0.12 and the good writes by this new version (0.12.1?).
