Phabricator updated HIVE-2607:
------------------------------
Attachment: HIVE-2607.D543.2.patch
kevinwilfong updated the revision "HIVE-2607 [jira] Add caching to json_tuple".
Reviewers: JIRA, heyongqiang
Added a new class of MetaStorePreEventListeners which are called before an
action is taken by the metastore. They are run before most validation and the
call to the Raw Store (after getting objects like partitons and tables where
convenient). These are hooks like MetaStoreEventListener implementations, and
are currently called on all functions for which MetaStoreEventListeners are
called, though this can change.
