------------------------------------
Summary: tcp retransmission issue seen in cassandra cluster
Key: CASSANDRA-10714
URL: https://issues.apache.org/jira/browse/CASSANDRA-10714
Project: Cassandra
Issue Type: Improvement
Components: Streaming and Messaging
Reporter: Jeff Liu
I have been seen tcp package retransmission issue in various stacks in our
environment. ( AWS with no VPC). I'm currently using hsha rpc server type on
cassandra 2.1.6 version. The information captured by wireshark shows that the
retransmission happened both between client-to-server and server-to-server.
Even within a cluster that doesn't have any client traffic, sporadic
retransmission still happens.
It's pretty easy to reproduce this issue by watching "netstat -s | grep
retrans".
