    Description

      This can happen if node to remove is not within cluster or rebalance api returns error for some reason and yet wait = true.

       

      from

            status, err := client.Rebalance(nodesToRemove)
       
            if wait {
       
              status.SetLogger(retryutil.Log(clusterName))
       
              return status.Wait()
       
            }
