> Resolution of this jira reduces usage of globals by adding a flag "isRequiredByAgent" in the config property object. If set to false, property will not be persisted on server.
>  Also some of the properties like dfs_datanode_port is no longer saved as global property but included in the service site (hdfs-site.xml) with a prefix ambari _ambari.dfs.datanode.port_and referenced from actual property _dfs.datanode.address_.
> *Note:* This Jira will resolve the usage of global in the ambari non-secure cluster. When going through security wizard, a bulk of non-used globals will be added. Attempt to improvise it is already going under AMBARI-2487.
