[jira] [Commented] (HIVE-22536) Improve return path enabling/disabling

    [ https://issues.apache.org/jira/browse/HIVE-22536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16981750#comment-16981750 ] 

Gopal Vijayaraghavan commented on HIVE-22536:
---------------------------------------------

[~mgergely]: a few years back, we broke backwards compat with a similar flag (the local fetchtask conversion being more/minimal etc). The "true"/"false" need to be accepted as valid values in the config or mapped to existing ones.

> Instead of having a boolean for hive.cbo.returnpath.hiveop it should be on/off/supported. In case of "supported" it should be used for a subset of commands which are already verified to be able to work with return path. This is a temporary solution for the time while we are developing return path, before making it the only way to handle commands.
