Subject Clustering configuration error -- HTTPS hostname wrong
Date Sun, 04 Dec 2016 23:34:35 GMT
Hello all,

I am trying to enable clustering on my NiFi instance, starting with the
original single-node instance which uses Kerberos and HTTPS.  I've been
following the Clustering Configuration section in the admin guide, and I
see in the logs that the node takes over as the Coordinator and elects the
dataflow.  When I try to connect to the UI I receive the below error -- it
looks like there is no hostname in the GET request when it tries to
replicate it?  I started up the second node and I see it join the cluster,
but accessing the UI throws the same erro -- failing to replicate the
request to both nodes.

Any ideas?

Thank you,
--Adam
