Change password screen shown on page refresh for autologin user
If an unauthenticated/autologin user accesses a public workspace dashboard on an Incognito tab and then refreshes or tries to reload the page, it can unexpectedly trigger the display of the Change Password modal.
Workaround:
To resolve this issue, change the autologin user's password once using the Change Password modal. After changing the password, the issue should no longer occur and the autologin functionality will work as expected.

Issue with impersonation in CDW Impala connections

You may see the following error while creating or editing the data connection to a CDW Impala or Hive Virtual Warehouse and using the connection details auto-populated from the CDW Warehouse drop-down:

User <username> is not authorized to delegate to <username>.

This happens because the Impersonation and Trusted Impersonation options are both enabled.

Workaround:

If the message appears when creating a new data connection, try refreshing the page. This will reset the Impersonation and Trusted Impersonation options.

If the message appears on the Edit Data Connection modal, copy the hostname, username, HTTP path, and other values present on the Advanced tab, and manually edit the existing CDW Hive connections. A manual edit will typically not trigger this bug.
