The only error in the logs is:
"[12/Sep/2013 02:52:24 +0000] settings INFO Welcome to Hue 2.5.0
[12/Sep/2013 02:56:08 +0000] spawning_controller INFO (10258) Child
died from signal 0 with code 1"

In CM, could you check the stderr/sdtoud logs of the processes? (to have
more details about the exception).

If nothing, could you try to start the Hue server manually from its home
and see?

e.g.
build/env/bin/hue runserver
build/env/bin/hue runcpserver

It is same error when access to /beeswax/.

[image: 埋め込み画像 1]

by the way, why the ldap access was used?
I enabled the Hue web server just after the Installation of the
Cloudera Standard.

Thanks,

LiLi

Maybe you are hitting a different bug.

Can you try to go on /beeswax/ instead of /about/ ?

[Adding hue-users; bcc: scm-users]

Can you attach the Hue log? (You can find that in CM -> Hue -> Hue
Server -> Log file. Or in /var/log/hue.)

Hi,

I want to enable HTTPS for the Hue web server.
I do it by following steps:

4. set Hue server with cloudera manager

5. save and restart the Hue server

6. access Hue Web UI
I got the error messages as following
