mesos-master crash with zookeeper cluster

Question

I am deploying a zookeeper cluster which has 3 nodes. I use it to keep my mesos master high availability. I download the zookeeper-3.4.6.tar.gz tarball and uncompress it to /opt, rename it to /opt/zookeeper, enter the directory, edit the conf/zoo.cfg(pasted below), create a myid file in dataDir(which is set to /var/lib/zookeeper in zoo.cfg), and start zookeeper using ./bin/zkServer.sh start, and it goes well. I start all the 3 nodes one by one and they all seems well. I use ./bin/zkCli.sh to connect the server , no problem.

But when I start mesos (3 masters and 3 slaves, each node runs a master and a slave), then the masters soon crashed, one by one, and in the webpage http://mesos_master:5050, slave tab, no slaves are displayed. But when I run only one zookeeper, these are all fine. So I think it's the zookeeper cluster's problem.

I got 3 PV host in my ubuntu server. they are all running ubuntu 14.04 LTS: node-01, node-02, node-03, I have /etc/hosts in all three nodes like this:

172.16.2.70     node-01
172.16.2.81     node-02
172.16.2.80     node-03

I installed zookeeper, mesos on all the three nodes. Zookeeper configure file is like this (all three nodes) :

tickTime=2000
dataDir=/var/lib/zookeeper
clientPort=2181
initLimit=5
syncLimit=2
server.1=node-01:2888:3888
server.2=node-02:2888:3888
server.3=node-03:2888:3888

they can be started normally and run well. And then I start the mesos-master service, using the command line ./bin/mesos-master.sh --zk=zk://172.16.2.70:2181,172.16.2.81:2181,172.16.2.80:2181/mesos --work_dir=/var/lib/mesos --quorum=2, and after a few seconds, it gives me errors like this:

sometimes the warning is like this, and then crashed with the same output above:

0817 15:09:49.745750  2104 recover.cpp:111] Unable to finish the recover protocol in 10secs, retrying

I want to know whether zookeeper is deployed and run well in my case, and How can I locate where the problem is. Any answers and suggests are welcomed. thanks.

Answer 1

Actually, in my case, It's because I didn't open firewall port 5050 to allow three servers to communicate with each others. After updating firewall rule, it starts to work as expected.
