Hello all,
We have been fighting some network/session disconnection issues between datacenters and I'm curious if there is anyway to enable tcp keepalive on the zookeeper/mesos sockets? If there was a way, then the sysctl tcp kernel settings would be used. I believe keepalive has to be enabled by the software which is opening the connection. (That is my understanding anyway) Here is what I see via netstat --timers -tn: tcp 0 0 172.18.1.1:55842 10.10.1.1:2181 ESTABLISHED off (0.00/0/0) tcp 0 0 172.18.1.1:49702 10.10.1.1:5050 ESTABLISHED off (0.00/0/0) Where 172 is the mesos-slave network and 10 is the mesos-master network. The "off" keyword means that keepalive's are not being sent. I've trolled through JIRA, git, etc and cannot easily determine if this is expected behavior or should be an enhancement request. Any ideas? Thanks much! -Jeremy
