May end up with a local 9160 connection if you are using cassandra-cli, cqlsh or hadoop on the node.
I also observed that local write latency is around 30-40 microsecond, while its takes around .5 miliseconds if the chosen node is not the node responsible for the key for 50K QPS
What CL ?
Can you just use netstat and dig into the process id and do a ps -ef |
grep <pid> to clear up all the confusion. Doing so you can tell which
process communicates with which process(I am assuming you are on linux.on
MAC or windows it is different commands).
Then, just paste all that in the email to this list so we can see it.
MY GUESS is someone is running a tool that is talking thrift on your
cassandra node???? Maybe another server like a web server?

The comments here so far are correct. Cassandra itself will never open
a thrift connection. Thrift is only for clients. Not sure what exactly
you are seeing but I don't think it's cassandra.

not only a node make connection to other nodes. i can also see nodes
connection to itself on port 9160.
