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
