I have reslove the problem.

as I posrt above ,I print the data struct

'ambari_db_rca_password':'123456',

I think it is a sting ,but when I print its type,it is a int type.

So I change the password to 'ambari',it is a sting,then every thing is goto OK!!!

Is still a problem of ambari

@darkz yu

Was there any errors while installation ?

Can you run the below command and paste the output here -

#ls -ltr /etc/hadoop

#ls -ltr /usr/hdp/current/

#hdp-select

Thanks

Did you upgrade your HDP from 2.0.6 to HDP2.3.4?

Why your logs are shwoing "/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/"

No,I am not upgrade HDP,just test upgrade ambari,when I met the error:

https://community.hortonworks.com/questions/24208/help-ambari-agent-registe-fail-with-netutilpy77-er...

and the problem is resolved now.

Then I install hdp,then met the error as I show in this topic

@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 ??

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.
