Here’s the scenario.
1. Deploy Nifi Cluster :
- NCM
- Pirmary
- Node.
2. Verified that everything is OK.
3. I then disconnected the slave Node and deployed some pipelines on the
cluster.
4. Now I tried to bring up the slave node. It gives the following error.

What I see is that the flow.tar file on the slave is 0 bytes. This does not
look right. Since the file on the NCM is about 20K bytes.
