I would suggest to check/share Hue server logs if there is any logging related to webhdfs calls. Login as Hue admin and update user permissions by selecting filebrowser.access.   Hope this helps.   Regards, Paras Was your question answered? Make sure to mark the answer as the accepted solution.

@BrianChan glad to know the issue is resolved. We do not recommend to disable kerberos once you have it enabled. The process is a complex one and we recommend to work with our support team if you have an active subscription. Also enabling kerberos for few services enabled is not supported. At high level, you need to work through https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/security-how-to-guides/topics/cm-security-using-cm-sec-config.html There are additional steps to delete znodes for hbase , the znodes for High Availability(HA) must be deleted if more than one JobTracker role is configured, the znodes for High Availability(HA) must be deleted if HDFS HA is enabled. Also ensure your /etc/krb5.conf remains same across all nodes if you are not managing this from Cloudera Manager.   Hope this helps, Paras Was your question answered?

@intelia_liem this error generally occurs when you request go to standby namenode and is generally not a cause of concern in HA setup. However if your job fails, please review the distcp command and use nameservice or active namenode for the requests.   Hope this helps, Paras Was your question answered?

@BrianChan  the part you highlighted is just a command parameter and not an error. Please check for errors in stdout and resource manager role logs as well. Also it would help if you can share the entire logs including stderr, CM agent and supervisord logs of the node. You will generally find issues at the end of file If this is a new cluster and you don't have issues with service downtime, I would also suggest to stop all services on the resource manager host and hard restart CM agent on the node. This will clear out any potential issues with supervisord staleness.   Hope this helps, Paras Was your question answered? Make sure to mark the answer as the accepted solution.
