Hi, I'm following this tutorial in order to install Cloudera Manager and CDH. The installation ends correctly, but I can't access to http://localhost:7180. Checking if the service has started:

[root@localhost cloudera]# service cloudera-scm-server status
/etc/init.d/cloudera-scm-server: line 109: pstree: command not found
cloudera-scm-server.service - LSB: Cloudera SCM Server

[root@localhost cloudera]#

I get the following errors every 15 seconds in /var/log/cloudera-scm-server/cloudera-scm-server.log:

I get response if I execute locally:
