> Protect against null ClusterStatus in HBase Client Service
> ----------------------------------------------------------
>
> Key: NIFI-5877
> URL: https://issues.apache.org/jira/browse/NIFI-5877
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.5.0, 1.6.0, 1.7.1
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Minor
> Fix For: 1.9.0
>
>
> 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.
