             Summary: Resource Manager. Params subtitution: allow dictionaries in dictionaries, allow default prefixes
                 Key: AMBARI-3656
                 URL: https://issues.apache.org/jira/browse/AMBARI-3656
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.5.0


1. Allowing dictionaries in dictionaries is very nessaccary since, configurations we will recieve from json have a lot of that.
2. We need to add default prefixes feature, because our configuration names are pretty huge, which will result in a very messy code
How it is now:
{code}
"${clusterHostInfo:configurations:yarn-site:yarn.log.server.url}"
{code}
how it should be:
{code}
env.set_default_prefixes(['clusterHostInfo.configurations.yarn-site',...])
"${yarn.log.server.url}"
{code}
