Description

I am seeing continuous disconnections and offer rejections in master's logs, its happening almost every 10-20 seconds

As per suggestions from various reads

I tried two approaches,

1. Setting --ip, --hostname and --port flags on the master and slave processes

Here's one of the master/slave process details (ps -ef output)

master:

/usr/local/sbin/mesos-master --ip=11.11.42.73 --hostname=mesosd-lapp01.mylab.com --port=5050 --work_dir=/mesos/data/master --log_dir=/mesos/logs/master --quorum=1 --zk=zk://11.11.42.73:2181,11.11.42.78:2181,11.11.42.79:2181/mesos

slave:

/usr/local/sbin/mesos-slave --ip=12.12.249.207 --hostname=pod1-08.mylab.com --port 5051 --work_dir=/mesos/data/slave --log_dir=/mesos/logs/slave --master=zk://11.11.42.73:2181,11.11.42.78:2181,11.11.42.79:2181/mesos --isolation=cgroups/cpu,cgroups/mem --cgroups_hierarchy=/cgroup --cgroups_root=/cgroup

2. I also tried specifying external IP and real hostname in /etc/hosts file e.g.

10.11.42.73 mesosd-lapp01.mylab.com in master host and
12.12.249.207 pod1-08.mylab.com in slave host

appreciate your timely response.
