Subject [jira] [Updated] (HIVE-12499) Add HMS metrics for number of tables and partitions
Date Tue, 08 Dec 2015 19:50:11 GMT


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

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.
