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 ?
R - represents read privilege. W - represents write privilege. X - represents execute privilege. C - represents create privilege. A - represents admin privilege. Thanks!
