Hi @Vamsi N the "Files" view in Ambari Views is a file explorer for HDFS. You should see it in the dropdown for the views. If you don't see it under the Ambari account you are using, you can use the instructions that Jay has above to add an instance of the Files view.

thanks Jay , reinstalling agent fixed this script. I will go ahead and deinstall the cluster using this script and then try to reinstall again. my cluster was running f ine until I deinstalled it and since then I am unable to get it up and running .

@timc c Can you also check the following properties and modify it according to your needs ? webhcat.proxyuser.knox.hosts * webhcat.proxyuser.knox.groups * As Jay pointed - once you set the appropriate permission restart all the necessary components + all hive services.

What is the reason behind separation into HDP and HDF? It is very often that company needs both real-time data processing and batch processing, why not to make single package?
