--------------------------------
I reslove the problem,Because the password of the account to access the ambari
database is a serial of number,so the server consider is a int object,I change
the pass to a string the problem is resloved...

> 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 post the problem in
