I have 3 zones and my initial cluster is :

- data-default in 2 zones
- data-highstorage in 2 zones
- ml in 1 zone
- kibana 2 zones

i changed the number of zones for 'ml' nodes to 2 zones instead of 1.  
and by doing so i need to use dedicated master nodes in 3 zones.  
but i get this error and the change failed.

// Cluster configuration change failed  
`Unexpected error during step: [validate-plan-prerequisites]: [no.found.constructor.steps.PlanValidationException: It is not possible to remove node attributes [data -> hot]]`

I tried to create a new cluster with :

- data-default in 2 zones
- data-highstorage in 2 zones
- ml in 2 zones
- kibana 2 zones
- master in 3 zones  
and it was OK.

why did the change not worked while creating a new cluster with the same configuration is succeeding ?

ECE version 2.2.1  
Elastic stack 7.0.0

and i'm using instance configurations tags:  
data:hot  
data:warm  
master:true  
ml:true

I think this is a known issue and the workaround is to run the same plan from the advanced editor and add `plan_configuration.transient.override_failsafe: true`

I believe you should only need to do that once
