Resolution: Duplicate
> Automatic invalidation of HMS metadata using Hive replication API (HIVE-7973)
> -----------------------------------------------------------------------------
>
> Key: IMPALA-3681
> URL: https://issues.apache.org/jira/browse/IMPALA-3681
> Project: IMPALA
> Issue Type: Sub-task
> Components: Catalog
> Affects Versions: Impala 2.6.0
> Reporter: Dimitris Tsirogiannis
> Priority: Minor
> Labels: catalog-server
>
> Hive is adding support for a replication API
> (https://issues.apache.org/jira/browse/HIVE-7973) that allows an HMS client
> to retrieve a global stream of HMS modifications made by all the HMS
> processes (in case of HMS HA). The Catalog server could use that API to
> automatically collect and update cached HMS metadata, thus eliminating the
> need for the user to call invalidate and refresh. This can only handle HMS
> metadata; file and block metadata will still need to be updated from the
> Namenode (e.g. by using inotify).
