             Summary: HTTP Site-to-Site can't update remote peer topology if the "bootstrap url" is down
                 Key: NIFI-2459
                 URL: https://issues.apache.org/jira/browse/NIFI-2459
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.0.0
            Reporter: Koji Kawamura


To establish a Site-to-Site protocol, a client NiFi uses the remote NiFi API url that is specified as 'URL' at the creation of a Remote Process Group (let's call it as 'bootstrap url').

Currently, HTTP Site-to-Site keeps using the same 'bootstrap url', even if the remote node goes down. If the bootstrap node went down, Site-to-Site data transfer will keep working, but it can't update remote peer topology.

RAW socket version cares about this scenario by asking updated peer information with every nodes that it has connected before, until it gets a successful response.

HTTP version should follow how RAW version handles this.
