I have added some print statement in the code where the exception is happening as i thought the issue was with python base64 encoding problem with padding. But looks like the the string passed to base64.b64decode() itself is malformed. See following log 2018-08-28 12:50:18,780:INFO:root:Syncing role definition 2018-08-28 12:50:18,800:INFO:root:Creating database reference Loaded your LOCAL configuration value: b'x393565452f683845463837555032666d5941577164673d3d' Traceback (most recent call last): File "/usr/hdp/current/superset/bin/superset", line 85, in <module> manager.run() File "/usr/hdp/2.6.4.0-91/superset/lib/python3.4/site-packages/flask_script/__init__.py", line 412, in run result = self.handle(sys.argv[0], sys.argv[1:])

@anarasimham, thanks for the info, Any reference to documentation stating this ?

vmaroli · ‎05-15-2018

I am using HDP 2.6.4 and Ambari 2.6.1.5. In Ambari HDFS summary page there is a metric called "Disk Usage (DFS Used)" which in case is showing 19GB. If I do a hdfs dfs -du -h / it is giving a total of 6GB. Shouldn't these two results be the same, or I am missing something here?
