Review request for Ambari, Jayush Luniya, Sumit Mohanty, and Sid Wagle. Bugs: AMBARI-16692 https://issues.apache.org/jira/browse/AMBARI-16692 Repository: ambari Description ------- RCA Database tables is not used anymore. This older, un-necessary data causes many Ambari DB queries to return more slowly than necessary. If the database gets large enough, it can have significant impact on the way ambari-server functions. The Ambari Server upgrade process should detect the presence of these older, deprecated tables, and automate the process of cleaning up this data.
