Sushil Kumar created NIFI-7003:
----------------------------------
Summary: "nifi.sh stop" makes a deleted node to join the cluster
in a disconnected mode
Key: NIFI-7003
URL: https://issues.apache.org/jira/browse/NIFI-7003
Project: Apache NiFi
Issue Type: Bug
Components: Configuration
Affects Versions: 1.10.0
Reporter: Sushil Kumar
As a process to descale the cluster, I did as following
{code:java}
nifi-toolkit/bin/cli.sh nifi disconnect-node
nifi-toolkit/bin/cli.sh nifi offload-node
{code}
once offloaded
{code:java}
nifi-toolkit/bin/cli.sh nifi delete-node
{code}
Now what happens is if I issue
{code:java}
nifi.sh stop{code}
command this node joins back the cluster as a disconnected node.
Found the relevant message in coordinator logs too
{code:java}
