- Changed how the appId is constructed. Using the substring till the first dash is too braod. - Modified it so it uses the substring all the way to the last dash (-). - Removed the max 3 limit on available racs. - Fixed sudo error when restarting cassandra. - Updated the Priam.properties file so it can update the correct cassandra config
