CM 5.5 failed to validate hue configuration with httpfs load balanced

matdba — Tue, 21 Apr 2026 13:53:37 GMT

Hello

we have deployed two httpfs in CDH 5.5.2 with CM 5.5.3 , and we have balanced the 2 services with an external loadbalancer, and populate in Cm => HDFS => scope = HttpFS the "httpfs Load Balancer" with loadbalancer:port. We tested it with curl and it's working like a charm.

After that in CM=> Hue , it's possible to choose the load balancer for browsing hdfs from hue, by the way, if it's selected, the CM will give an error of "configuration error:null".

As workaround we used the safety valve to define the loadbalancer web url.

Any idea ? Do we have hit a bug of CM ?

Kind Regards

Workaround : insert in the safety valve hue.ini in CM :ìthe follow rows :

[hadoop]
[[hdfs_clusters]]
[[[default]]]
webhdfs_url=http://loadbalancer_httpfs_server_fwdn_name:14000/webhdfs/v1/
