To remove a node from 2 node cluster in AWS I ran
nodetool removenode <Host ID>
After this I was supposed to get my cluster back if I put all the cassandra.yaml and cassandra-rackdc.properties correctly.
I did it but still, I am not able to get back my cluster.
nodetool status is displaying only one node.
significant system.log on cassandra is :

cassandra-rackdc.properties: https://pastebin.com/xmmvwksZ
system.log : https://pastebin.com/2KA60Sve
netstat -atun https://pastebin.com/Dsd17i0G
Both the nodes have same error log.
All required ports are open.
Any suggestion ?
