>                 Key: NIFI-2944

>             Project: Apache NiFi
>          Issue Type: Improvement
>    Affects Versions: 1.0.0
>            Reporter: Joseph Percivall

> Currently NiFi doesn't do any validation on what is set for "nifi.remote.input.host". For example, I ran across 1 node cluster configured with a remote input hostname that started with a "http:// ...". This cluster started up and everything seemed fine on it's end but on the client side it failed.
> After the initial connection it received "http:// ..." as the hostname for it to connect to causing UnknownHostExceptions.
> NiFi should validate that the value set for the remote input host is valid in order to avoid this issue.
> Example:
