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. ...

I have try to use an new virtual machine install the new ambari-agent version 2.2.1,but when I start server on that virtual machine,the ,og still told me : File "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-START/scripts/params.py", line 141, in <module> ambari_db_rca_password = config['hostLevelParams']['ambari_db_rca_password'][0] TypeError: 'int' object is unsubscriptable So I think there must be something wrong about the ambari-agent code. May be the basic ambari-agent python lib change lead the problem?? PS: I use the local ambari and hdp repo. ... View more

@Sagar Shimpi @Divakar Annapureddy @gor don I modifythe code of /var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-START/scripts/params.py and find line 141: ambari_db_rca_url = config['hostLevelParams']['ambari_db_rca_url'][0] I add import pprint print "xxxxxxxxxxxxxxx" pprint.pprint(config['hostLevelParams']) print "xxxxxxxxxxxxxxx" to debug the dictionary content: {'agentCacheDir': '/var/lib/ambari-agent/cache', 'ambari_db_rca_driver': 'com.mysql.jdbc.Driver', 'ambari_db_rca_password': '123456', 'ambari_db_rca_url': 'jdbc:mysql://127.0.0.1:3306/ambari', 'ambari_db_rca_username': 'ambari', ... So I think it call wrong,so I change ambari_db_rca_url = config['hostLevelParams']['ambari_db_rca_url'][0] to ambari_db_rca_url = config['hostLevelParams']['ambari_db_rca_url'] then start the service is OK. so I think is a bug of ambari-agent ?? ...
