Hi @yellowD,   From the output, it looks like you are using CDH5.15.1. Please confirm if it is not.   Starting from CDH 5.12.2, 5.13.1, or later versions of CDH, it is no longer necessary to export the HUE_CONF_DIR, HUE_DATABASE_PASSWORD, and HUE_IGNORE_PASSWORD_SCRIPT_ERRORS environment variables.   Instead, from the Hue sever, run the following as the root user (due to security settings of CM process directories): /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue changepassword <USER-TO-CHANGE> --cm-managed So if you want to change the password for user named "admin", then run the command like this: /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue changepassword admin --cm-managed   See my test result below: # /opt/cloudera/parcels/CDH/lib/hue/build/env/bin/hue changepassword admin --cm-managed Changing password for user 'admin' Password: Password (again): Password changed successfully for user 'admin' Thanks and hope this helps, Li   ...

Postgres is sensitive to how you connect to it. You should be using the exact address it listens on, as only that will be allowed by the default configuration. Your command carries an IP that's 0.0.0.0. While am uncertain if you've masked it or if you are truly using a wildcard-designate IP for a server address, you should ideally be using the exact hostname/IP that the Postgres service is listening on. Your Postgres service's configuration will carry the listening_address entry in it that designates this. Take a look at this thread over at Stack Exchange: https://dba.stackexchange.com/a/84002 ...
