You can find with this code in terminal:

yarn node -list -all

And you can see details of nodes (Node-Id,Node-State,Node-Http-Address,Number-of-Running-Containers)

 hdfs dfsadmin -report

The above command will give you active and dead nodes. Even the namanode web UI 50070 will also give you the count of datanodes live or dead
