Apache Pinot

Thanks! We're on pinot 4 so should I just go to zookeeper and manually delete the tag somehow?

Here is the current zk value for the node:
``` get /pinot/CONFIGS/PARTICIPANT/Server_pinot-server-5.pinot-server-headless.pinot.svc.cluster.local_8098
{
  "id" : "Server_pinot-server-5.pinot-server-headless.pinot.svc.cluster.local_8098",
  "simpleFields" : {
    "HELIX_ENABLED" : "true",
    "HELIX_ENABLED_TIMESTAMP" : "1596492023697",
    "HELIX_HOST" : "pinot-server-5.pinot-server-headless.pinot.svc.cluster.local",
    "HELIX_PORT" : "8098",
    "adminPort" : "8097",
    "shutdownInProgress" : "false"
  },
  "mapFields" : { },
  "listFields" : {
    "TAG_LIST" : [ "DefaultTenant_OFFLINE", "DefaultTenant_REALTIME" ]
  }
}```

Do I just delete it or do I edit something?

either works:
```"TAG_LIST" : [  ]```
or
```"TAG_LIST" : [ "untagged_OFFLINE" ]```
(latter helps with operations. You can see how many you have untagged
