Subject [jira] [Commented] (CASSANDRA-14615) Node status turns to UN although thrift and native transport port are not open to listen
Date Wed, 01 Aug 2018 16:03:00 GMT


Anshu Vajpayee commented on CASSANDRA-14615:


Thanks, I understand  - U means process is up and N is normal .  Normal here represents 
Node is part of cluster and started gossiping. (gossip status is true)

But I believe,  it would be more appropriate  if node reports normal status once all ports
are also open, because after port open node will be actual normal for clients.  Isn't it a
literal meaning of  "normal" ?  

Currently "N" in UN" status is not suitable for  end users/operators point of view  as it
only tells gossip status.  It is misleading. 


I know there are various command to check the  port status as you mentioned  like nodetool
gossipinfo or nodetool info. 

With this current N explanation,  I don't see any significance of nodetool status command
because much better  details (including port status,gossip status and state)  I can get
from nodetool info and nodetool gossipinfo .

I think it would be more appropriate if N in UN represents Normal  once all ports are also

> During startup , Node status turns to UN but not having the thrift and native transport
ports open.  It is misleading. 
> As per our understanding UN stands : node is up and running fine and ready to connect
from  clients. 
> It would be more appropriate if node shows UN status only when ports are open for client
