how to exclude new data node machines from the cluster even they are up

hi all

 

we have HDP 2.6.4 cluster with 365 data-nodes ( workers machines ) 

 

we intend to add to this cluster 67 new data-nodes ,

 

but for now these new data-nodes should not be active , in spite the Linux OS is up and machine is up

 

so is it possible to disable HDFS and YARN on these new machines? 

 

what is the preferred way? 

 

for example - decommission ? , or just maintenance mode? or maybe both them? 

 

the target is to avoid from spark jobs to run on the new data-nodes machines and disable the HDFS Temporarily

@mike_bronson7 The similar discussion happened on one of other Community thread by @Shelton You can follow this here:

Also the decommissioning is more suitable approach you can see this doc more more details though:
