Subject [jira] [Commented] (NIFI-7246) JWT Generated by a node in the cluster is not honored by other nodes in the cluster.
Date Sun, 15 Mar 2020 09:26:00 GMT

    [ https://issues.apache.org/jira/browse/NIFI-7246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17059589#comment-17059589

Shreyas KC commented on NIFI-7246:
----------------------------------

[~pvillard]  We create flows through NiFI APIs based on the metadata definition of the pipeline.There
is a microservice stack which does that. 

The cluster is setup using 3 nodes. 

We have an external load balancer. 

Without having a mechanism to share Token, we need to have a sticky session in place and we
will end up spiking a single node with all the requests. It makes sense to load balance across
all the nodes. Which would result better efficient execution. 

This is also applicable in monitoring the cluster, flows etc.

let me know if it makes sense.

> In an externally load balanced cluster without sticky session, it is not possible to
currently share the JWT generated by one node with the rest of the nodes in the cluster.
> Hence we need a mechanism where we can introduce static key in the nifi.properties in
its chosen by the cluster administrator.
