----------------------------------
Summary: Host registering failure from primary/agent os checking
on centos6
Key: AMBARI-4523
URL: https://issues.apache.org/jira/browse/AMBARI-4523
Project: Ambari
Issue Type: Bug
Components: agent
Affects Versions: 1.4.3
Environment: centos6 for all hosts
Reporter: Perry Tian
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.
