Review request for Ambari and Dmytro Sen.


Bugs: AMBARI-4523
    https://issues.apache.org/jira/browse/AMBARI-4523


Repository: ambari


Description
-------

I am using Ambari (1.4.3.38) for hadoop cluster installation and management. All the cluster
nodes are built on centos 6.0.

During the ambari server installation, ambari-server recognized the primary/cluster os as
redhat6 (see ambari.properties). 
During the ambari agent bootstrap/host register, ambari-agent regonized the agent os as centos
linux6 (see log). 

>From log files (ambari-server.log, ambari-agent.log), I found the inconsistence caused
the warning of ambari-agent bootstrapping and failure of host registering.

I'm still not sure why this happen, but I guess it's caused by the differene of os checking
methods among ambari server side code, ambari-agent bootstrap script (os_type_check.sh,based
on os release file) and registering script (Controller.py/Register.py based on os hardware
profile) .

I just share to see if anyone can fix the issue.

BTW, for me, to solve the problem, I manually edited the script files to make it work temporarily:

To avoid warning of agent bootstrapping, in os_type_check.sh, add current_os=$RH6 above the
echo line or add res=0 after case statement;
To make the node register work, in Controller.py, add data=data.replace('centos linux','redhat')
before sending registering request;

Thanks.
