T Jake Luciani updated CASSANDRA-6702: -------------------------------------- Fix Version/s: (was: 1.2.19) 2.0.11 > Upgrading node uses the wrong port in gossiping > ----------------------------------------------- > > Key: CASSANDRA-6702 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6702 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: 1.1.7, AWS, Ec2MultiRegionSnitch > Reporter: Minh Do > Priority: Minor > Fix For: 2.0.11 > > > When upgrading a node in 1.1.7 (or 1.1.11) cluster to 1.2.15 and inspecting > the gossip information on port/Ip, I could see that the upgrading node (1.2 > version) communicates to one other node in the same region using Public IP > and non-encrypted port. > For the rest, the upgrading node uses the correct ports and IPs to > communicate in this manner: > Same region: private IP and non-encrypted port > and > Different region: public IP and encrypted port > Because there is one node like this (or 2 out of 12 nodes cluster in which > nodes are split equally on 2 AWS regions), we have to modify Security Group > to allow the new traffics. > Without modifying the SG, the 95th and 99th latencies for both reads and > writes in the cluster are very bad (due to RPC timeout). Inspecting closer, > that upgraded node (1.2 node) is contributing to all of the high latencies > whenever it acts as a coordinator node. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
