@Aditya Mamidala Try to make configuration changes with Yarn user? use below commands to login as yarn: su - root and then su - yarn

@Aditya Mamidala Are you managing hadoop services through ambari or it's manual installation? if it's ambari managed cluster, you have to make configuration changes through ambari only, otherwise your changes will overwrite by Ambari

@rakesh kumar I hope this will help you. if you are an admin, you need to have full access on data base and tables as well to create,drop,update,alter tables. Even if you want to drop DB you should able to do it. if you are a developer, you will get limited access to do only your work at tables level.

Hi, quick question -- do we have any front-end for Python (like we have R Studio for R)? Thanks, Divakar

@PJ It's hard to tell but I would suggest you to go with hot fix when you don't have time to validate all your production jobs with HDP2.5.0 stack if you have time I would suggest you to install HDP2.5.0 in your Dev environment first and test all you production jobs, ensure that all are running with out having any issue.
