DetectDuplicate : java.net.ConnectException
Hi,
Iam new to Apache Nifi and Iam trying it out on my Windows machine. When I use the DetectDuplicate processor, I get java.net.ConnectException. How can I start DistributedMapCacheClientService?
Thanks,
Arathi

Hi Matt,
Thanks a lot! DistributedMapCacheClientService is working now.

Arathi,
You'll need to add another Controller Service, one of type DistributedMapCacheServer, set up on port 4557 (to match your DistributedMapCacheClientService), and enable/start it. Then you should be able to connect successfully.

Matt

Hi Adrin,
I already created an instance of the DistributedMapCacheClientService with the server hostname pointing to localhost and port 4557. I use this service in the
“Configure Processor” dialog of “DetectDuplicate” processor. But when I execute the workflow, I get java.net.ConnectException in Bulletin board.
Could you tell me if I missed anything?
Thanks,
Arathi

Hi Arathi,
Welcome to the NiFi community. The DistributedMapCacheClientService works in tandem with the DistributedMapCacheServer. Creating an instance of that Controller Service will let you configure the associated properties which can then also be entered for your client, DistributedMapCacheClientService, listed above.
Please let us know if you run into any issues.

Hi Bryan,
How can I setup a DistributedMapCacheServer?
Thanks,

Hello,
DistributedMapCacheClientService requires a DistributedMapCacheServer to be setup first.
You then point the client service at the host (most likely local host in your scenario) and port of the server.
Let us know if that doesn't help.
