After I had updated HDP from 2.5 to 2.6 the Atlas Metadata Server Web UI failed due to no permission was granted to account 'atlas' on the HBase detault table 'atlas_titan'.
I manually granted the 'full' permission to atlas with following shell command, then restarted Altas, problem solved.
...> grant 'atlas', 'RWXCA', 'atlas_titan'
The question is do I really need grant 'atlas' all those privileges of RWXCA ?
Thank you on the insight on the permissions.
The atlas_titan table is the repository for all of Atlas' data. All operations performed via the Atlas web server end up interacting with this table and the ATLAS_ENTITY_AUDIT_EVENTS table.
Is there any specific concern around granting permissions?
Hope this helps.
Thank you Ashutosh.
No, I do not have a specific concern at this moment. I just want to make sure to give the minimum permission needed.
