I have a 44 node cluster and I will have to put the slave nodes in maintenance mode and shut them down. Will be getting during when the slaves are shutoff?
Please, please help.
Assuming you want to put slave services in Maintenance Mode in Ambari before you stopping the services
Go to the service -> service Actions -> Turn on Maintenance Mode.
Please refer the below screen shot:

Hi @subhash parise,
Thank you! No alerts were observed after the maintenance mode was enabled.
