HUE no longer show databases in Impala after moving catalog server

scratch28 — Tue, 21 Apr 2026 13:54:51 GMT

My Impala catalog server decided to not restart (different problem)

so I removed the service from one node and started in another

Now HUE does not show any databases and cannot execute any sql in Impala through HUE

I am able to run via command line in Impala-shell fine

So I guess my question is in Cloudera Manager - How do I tell HUE or the server HUE is on there is a new catalog server?

All I see is

Impala Service

Hue (Service-Wide)

the choices of

Impala or none

Not very configurable

Did you restart Hue?

I restarted HUE --Impala via HUEdoes not see databases

then I went to Cloudera Manager disabled Impala restarted HUE enabled Impala restarted HUE -Impala via HUE does not see databases

then I went to Cloudera Manager restarted Impala, Hive and HUE - Impala via HUE does not see databases

Per support in another thread

The last time I saw this issue, it was due to something cached in the browser used to access Hue. Can you try using another browser to see if the problem happens there?

If so, you might try logging out of Hue, clearing your cache, then logging into Hue to see if that helps.
