----------------------------------
Fix Version/s: 2.0.0
Resolution: Fixed
> ElasticSearchClientService fails config verification with Nullpointer before
> first enable
> -----------------------------------------------------------------------------------------
>
> Key: NIFI-12891
> URL: https://issues.apache.org/jira/browse/NIFI-12891
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Bob Paulin
> Priority: Minor
> Fix For: 2.0.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> If a user clicks the "Verify Properties" button before the
> ElasticSearchClientService Controller Service is first enabled it fails to
> verify the connection. This is due to a null pointer that occurs because
> both the responseEncoding and objectmapper is not set in the verify method
> before the test. This gives the user the incorrect error that the connection
> failed even though the connection would have succeed.
>
> Recommend managing these variables in the verify method.
