how to join worker/kafka machine to ambari cluster after machine deleted by mistake

worker08 machine was deleted by mistake from ambari cluster ( by host action --> delete host )

now we want to join this machine again to the ambari cluster

we cant use the option from the ambari ( add new host ) , because this option is for new machine and not for machine that already installed as in our case

* worker08 is already installed with (datanode , nodemanager , matrix monitor and all client components )

is there any API command to do the join process on worker08?

Hi Michael
Yes you can use Blueprints
1 - Export blueprints via API call ( GET /api/v1/clusters/:clusterName?format=blueprint )

2- change the json document

3- Import again the new modified BluePrint json ( POST ... )

For more details about how to use blueprints, please check here
