How do i check the status of cassandra nodes?

As this a training setup only one node is being used, for real use you would have a Cassandra cluster, consisting of many nodes.

$ nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
--  Address    Load       Tokens       Owns (effective)  Host ID                               Rack
UN  127.0.0.1  171.3 KB   256          100.0%            1baa34tf-1965-1w40-a322-eb08b1267x58  rack1

UN - The U mean Up and the Normal.

If you have a cassandra cluster: There will be more nodes.

$ nodetool status
Note: Ownership information does not include topology; for complete information, specify a keyspace
