     Like STRAM, streaming containers also need to communicate with NameNode to use HDFS persistence
for reasons such as saving the state of the operators. In secure mode they also use NameNode

    +Clients connects to STRAM and make web service requests to obtain operational information
about a runtime application. When security is enabled we want this connection to also be authenticated.
In this mode the client passes a web service token in the request and the STRAM checks this
token. If the token is valid, then the request is processed else it is denied.
