@Qian,
I think you're running issues with firewall, did you make sure your master can
reach from each other?
FROM master A
$ telnet B 5050
I think it fail to connect.
Please ensure shutdown any firewall.

Hi, @Qian Zhang Your issue reminds me of this

which I could not reproduce in my env. I am not sure whether your case are
same with Stefano or not.

I deleted everything in the work dir (/var/lib/mesos/master), and tried
again, the same error still happened :-(
Thanks,

The extra zookeepers listed in the second argument will let you mesos
master process keep working if
its local zookeeper goes down for maintenance.

I have an Open DC/OS environment which is enabled master HA (there are 3
master nodes) and works
OK, good - that part looks as expected, you've had a successful
election for a leader
(and yes that sounds like your zookeeper layer is ok).
You need the 2nd command line (i.e. you have to specify all the zk
nodes on each master, it's
not like e.g. Cassandra where you can discover other nodes
My 2cents - Is there a possibility of old data in /var/lib/mesos - can you
try deleting the folder /var/lib/mesos in all the 3 systems and try
bringing it up??

Which version are you using?

Thanks Vinod and Dick.
I think my 3 ZK servers have formed a quorum, each of them has the
following config:
$ cat conf/zoo.cfg
server.1=192.168.122.132:2888:3888
server.2=192.168.122.225:2888:3888
server.3=192.168.122.171:2888:3888
autopurge.purgeInterval=6
You told the master it needed a quorum of 2 and it's the only one
online, so it's bombing out.
That's the expected behaviour.
You need to start at least 2 zookeepers before it will be a functional
group, same for the masters.
You haven't mentioned how you setup your zookeeper cluster, so i'm
You need to start all 3 masters simultaneously so that they can reach a
quorum. Also, looks like each master is talking to its local zk server, are
you sure the 3 ZK servers are forming a quorum?
