So to confirm: this is a clean install of Ambari 2.2.1.0, not an upgrade from a previous Ambari?

What OS are you using?

cc @mahadev

My OS is centos6.5 and I not an upgrade Ambari

[#4]

Would you mind posting the content of your /etc/ambari-server/conf/ambari.properties file? Also provide the output of "ambari-server --version" and "ambari-server --hash". Thx

[#5]

# ambari-agent --version

2.2.1.0

# ambari-agent --hash

@darkz yu

Are you able to start the concerned service manually on the given node? If so, please go ahead and file a technical support case / bug. Upgrade to 2.2.1.1 if possible.

After I change the ambari-agent side python code of file:

"/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-START/scripts/params.py"

as the contents I post above,I can start service on the host which the agent is installed through the ambari-server web gui.

So I think it must be a bug,but I check the same file of the agent at version 2.1,the code is the same and the dumped data structure in the memory is the same between two versions.So I don't know what differents lead the problem.

/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-START/scripts/params.py

How to modify params.py file ? you can start service

[#10]

I post it above

[#11]

I reslove the problem ,because the password of the account which ambari to access mysql is a pure number, the code read the type to int but not a sting . change your password and every thing is ok.
