There was a problem hiding this comment.
Could we assert the node is not-null in the place where the NPE was happening? Would have been good to see it as an immediate failure at that point, let's avoid any recurrence and document the assumption here.
Otherwise LGTM (one typo nit) no need for another review.

An NPE is thrown when executing
disassociateDeadNodesfor a node that ispresent in a desired balance failing corresponding master state update task.
As a result this node can no longer join cluster after restarting as it
remains in a cluster state.
