Hue Runcpserver Log Empty

Hello,

We were getting ‘DatabaseError: ORA-01017: invalid username/password; logon denied’ post our db upgrade, to fix that we have reset the hue password, which worked and that issue got fixed.

Unfortunately one of our guys deleted a couple of logs from /var/log/hue. We have recreated runcpserver.log with the necessary permission, and restart Hue server, yet we fail to see the file being populated (file is still empty).

 

Request assistance / guidance in fixing this issue.

 

Thanks

Wert

@wert_1311 If this is CDH6 or later you might be hitting a known issue with this. Here is the solution. 

To resolve this issue, do the following on every Hue server:

#RHEL/Centos
/usr/sbin/alternatives --install /etc/hue/conf hue-conf /opt/cloudera/parcels/CDH/etc/hue/conf.empty 10

This issue occurs if the upgrade does not create or re-create the alternatives for hue-conf to point to /opt/cloudera/parcels/CDH/etc/hue/conf.empty/.

@wert_1311 No downtime needed. Only agent CM agent restart on Hue servers may required if you see the alternative not taking effect.
