After deployed Impala Virtual data warehouse of Data service.

I faced Error "401 client Error: Unauthorized for url: http://coordinator:28000/cliservice"

Sometimes It works well. 

 

To solve this problem what should I check?

I got the reason. 

When enter the LDAP information 

I had to use port 3268

For example ldap://ad.server.host:3268 instead of ldap://ad.server.host:389

Hi @Hae to start with troubleshooting the problem, we should analyse following logs, so check we find a start point what might be causing the problem

--> Impala coordinator POD logs

--> HUE backend POD logs

--> HUE Frontend POD logs

401 error shows issue might be related to authentication, so will recommend to check if there is any changes done on LDAP

Are you facing problem on periodic basis?
