Szehon Ho updated HIVE-12499:
-----------------------------
Attachment: HIVE-12499.2.patch
Take the review feedback from Lenni/Jimmy to not issue periodic queries to the
metadata store. New strategy is to do it once at startup, and then from then
on listen to events to get delta counts.
This change thus splits the metrics into 'init' and 'delta' counts for metadata
and user can infer the total number. It is not possible for us to give a total
as there may be other HMS active in the cluster.
> Add HMS metrics for number of tables and partitions
