>             Project: Apache NiFi
>          Issue Type: Improvement
>    Affects Versions: 1.7.1, 1.6.0, 1.5.0
>            Reporter: Bryan Bende
>            Assignee: Bryan Bende

> We currently get the masterAddress with this line of code:
> {code:java}
> masterAddress = admin.getClusterStatus().getMaster().getHostAndPort();{code}
> If getClusterStatus() returns null, or getMaster() returns null, then this code will throw a NPE and the service will fail to enable.
> We only user the masterAddress for the transit URI of provenance events, and we already protect against a blank/null masterAddress when generating the URI, so we should protect against the possible nulls in the line above.
