How to use wait\notify Processor?

Question

I have running nifi instance 1.2.0.

I just tried to use \"Wait\\Notify\" Processor with following reference http://ijokarumawak.github.io/nifi/2017/02/02/nifi-notify-bat

Answer 1

You will need to create and start a DistributedMapCacheServer and DistributedMapCacheClient. The client needs to be configured with the port and host that the server is listening on.

Then the Wait and Notify processors use the DistributedMapCacheClient.

Since you were able to start the processors, you likely already have the client setup, but you don't have the server running.
