This is a bug. There are a mismatch between documentation, nifi.properties
and the java class handling the properties

Looking at the code, it appears that if nifi.cluster.load.balance.address
is not set, it falls back to choosing nifi.cluster.node.address.  If this
is not provided, it finally falls back to localhost.

I'd recommend setting nifi.cluster.node.address at minimum, and you might
as well also set nifi.cluster.load.balance.address in order to be explicit.

Hi Joe

I just found out that port 6342 is bound to localhost. Why
In the last build NIFI is bound to localhost as standard if not specifying
which interface to use:
nifi.web.https.host=node1.domain.com
nifi.web.https.port=8443
nifi.web.https.network.interface.default=ens192<- If this is not
configured the UI is bound to localhost.

But how can I configure port 6342 to bound to any interface???

kind regards

 Thanks for replaying :-)
 Looking at status history for the fetchFTP and all the other processers
 in the flow it is only the primary node which has processed flowfiles.
 I have created clusters before with no issues, but there must be
 something tricky which I'm missing.

 I found this error in the log which explain why it is only the primary
 node
 2021-06-10 16:00:22,078 ERROR [Load-Balanced Client Thread-1]
 org.apache.nifi.controller.queue.clustered.client.async.nio.NioAsyncLoadBalanceClient
 Unable to connect to node3.domain.com:8443 for load balancing
 java.net.ConnectException: Connection refused

 But I don't know why the Connection should be refused. I can't find any
 other errors about connections. And know I have added the node group into
 all policies, so all nodes should have all access rights.

 Any advice for future investigation?

 Jens

 Out of curiosity, when you run the FetchFTP processor, what does the
 Status History of that processor show?  Is the processor processing files
 on all of your nodes or just the primary?

Hi Joe

Thanks for replaying :-)
Looking at status history for the fetchFTP and all the other processers in
the flow it is only the primary node which has processed flowfiles.
I have created clusters before with no issues, but there must be something
tricky which I'm missing.

I found this error in the log which explain why it is only the primary node
2021-06-10 16:00:22,078 ERROR [Load-Balanced Client Thread-1]
org.apache.nifi.controller.queue.clustered.client.async.nio.NioAsyncLoadBalanceClient
Unable to connect to node3.domain.com:8443 for load balancing
java.net.ConnectException: Connection refused

But I don't know why the Connection should be refused. I can't find any
other errors about connections. And know I have added the node group into
all policies, so all nodes should have all access rights.

Any advice for future investigation?

kind regards
Jens

Hi Jens,

Out of curiosity, when you run the FetchFTP processor, what does the Status
History of that processor show?  Is the processor processing files on all
of your nodes or just the primary?

Round Robin not working NiFi 1.13.2

2021-06-10 Thread Jens M. Kofoed
Dear community

I have created a 3 node cluster with NiFi 1.13.2, java 8 on a ubuntu 20.04.
I have a ListFTP Process running on primary node only -> FetchFTP with
Round Robin on the connection. But if I stop the FetchFTP Process and
looking at the queue all flowfiles are listed to be on the same node. Which
is also the primary node.

Just for testing purpose, I've tried to set round robin on other connection
but all files stays on primary node. I have been looking in the logs but
can't find any errors yet.

Please advice?
kind regards
Jens
