Removing Multiple Nodes from a Cluster
Remove multiple nodes from a Big Data Service cluster.
Note
When you remove a node, Big Data Service decommissions the node before deleting it. However, if the decommissioning process doesn't finish in the 40-minute time limit, the request fails. Time taken to decommission a node depends on the number of blocks in the node that need to be moved. Therefore, we recommend that you decommission a node before removing it from the cluster.
