NIFI : Cluster with Multiple Instance

[#1]

Hello all,

I've trying configure two instances NIFI in the same cluster (3 nodes)

My configuration :

Instance 1 :

-bash-4.1# grep port conf/nifi.properties
nifi.remote.input.socket.port=10443
nifi.web.http.port=
nifi.web.https.port=9443
nifi.cluster.node.protocol.port=11443

-bash-4.1# more conf/zookeeper.properties

clientPort=2181

server.1=nifi001:2888:3888
server.2=nifi002:2888:3888
server.3=nifi003:2888:3888

Instance 2 :

-bash-4.1# grep port conf/nifi.properties
nifi.remote.input.socket.port=10444
nifi.web.http.port=
nifi.web.https.port=9444
nifi.cluster.node.protocol.port=11444

-bash-4.1# more conf/zookeeper.properties

clientPort=2182

server.1=nifi001:2889:3889
server.2=nifi002:2889:3889
server.3=nifi003:2889:3889

It's missing some things, because my nifi002 and nifi003 can joint the cluster.

There could be many other things wrong, but in your ZooKeeper properties, the servers should be the same on every node. If instance #1 is pointing to 2888:3888 for all three ZK servers, then instance #2 and #3 should also be pointing to the same thing.

Thanks @Bryan Bende

Perpahs, it was not cleared, I want to start 2 instances nifi with the same cluster (node1, node2, node2)

so I would have 2 url

==> https://node1:9443 (instance1 ==> canva1)

==> https://node1:9444 (instance2 ==> canva2)

It is possible ?

I have related question: how to deploy multiple nifi components to all the HDF cluster nodes. And, then the question to ask is just like you ask above. I use Ali's HDF ambari-bootstrap blog's approach to automatically deploy the blueprint-based HDF 2.0.1 cluster. But, it has only one NIFI in one of the specific node within the HDF cluster. I am trying to figure our how to deploy NIFI to all the HDF cluster node.

I'm not sure I understand the question..

Are you asking if you can run two NiFi clusters on the same physical hardware?

If so, what would be the reason for doing this?

[#6]

I've 4 teams, i would have one canva per team.

The way to set this up in Apache NiFi 1.0.0 is to use a single NiFi cluster with process groups for each team, and restrict the permissions appropriately so that members of a team can only work with in their given process group.

See the "Multi-Tenancy" section of this post for an example:
