Subject [jira] [Comment Edited] (ATLAS-597) Handle Cluster renaming

-----------------------------------------------------------------

Cluster entity

The cluster entity will have the following properties

name
description
list<string> aliases - This will hold older cluster names or previous aliases
 

Hook changes for Entity updates/creates /deletes

This also means that the hooks will have to pass the qualifiedName in entity creates/updates/deletes
 as  "dbName.tableName@clusterId" instead of the "dbName.tableName@clusterName"

> Cluster name could easily be changed by users which is used in qualified names to dedup
entities. For eg: hive_table as <dbName.tableName@clusterName> . Hence all entities
will be recreated if they are renamed unless a mass update on repository is done with new
cluster name.
> Hence cluster  should be represented by an id which is constant and tied to clusterName
which could change
