[jira] [Commented] (PHOENIX-5422) Use Java8 DateTime APIs instead of joda-time APIs

["Istvan Toth (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-5422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17703201#comment-17703201 ] 

Istvan Toth commented on PHOENIX-5422:
--------------------------------------

My current understanding is that we cannot ditch Joda while maintaining backwards compatibility, without re-implementing chunks of its functionality.

The way I see forward is to make much of the date handling functionality pluggable, implement a new standard-compilant module based on java.time, and confine joda to a legacy module for backwards compatiblity

> currently, phoenix-hive.jar bundles an old version of joda-time library. Java8 has new DateTime APIs are similar in to the joda-time APIs in features. It would make sense to eliminate a dependency on external library that may or may not be
> a) Actively developed
> b) not guaranteed to be backward compatible with older APIs and could involve code changes as well.
> Its is better to move using JDK8 APIs.
