Description

As a process to descale the cluster, I did as following

 

nifi-toolkit/bin/cli.sh nifi disconnect-node
nifi-toolkit/bin/cli.sh nifi offload-node

 

once offloaded

 

nifi-toolkit/bin/cli.sh nifi delete-node 

 

Now what happens is if I issue

nifi.sh stop

command this node joins back the cluster as a disconnected node. 

Found the relevant message in coordinator logs too
