Hi,

The hue services fail to start on the cloudera cluster CDH5.

Below is the error of std.err file....

/opt/cloudera/parcels/CLDH5-5.2.6-1.cdh5.2.6.p0.2/lib/hue/build/env/bin/hue sycdb  --noinput... /usr/bin/env: python2.6: No such file or directory...

Can someone help here?

Thanks,

Narayana

Hi Narayana,

   Do you have python2.6 installed on that node ?

To check the version, you can run 

`which python` --version

Hi,

Python is installed... the output of the command is

Python 2.6.6

Is the executable in /usr/bin ? If not, you can link it to '/usr/bin/' and try restart Hue service again.

CLDH5-5.2.6-1.cdh5.2.6.p0.2, is it a custom parcel? How did you install it?

You would probably need to install the mysql-dev packages, e.g. https://github.com/cloudera/hue#development-prerequisites

Hello Romain,

In the CM page, all services are shown as green dot including hue... Now when I click on Hue Web UI (hostname:8888), i get page can't be reached error...

Few things:

on the machine where hue is installed from Cloudera Manager.. there is nothing listening on Port 8888

From Cloudera Managera, if I add Hue as a service and start it.. Is it enough or do I need to do additional installation.

do you have any document reference to guide on this.

Thanks,

Narayana
