Mesos can connect to an existing ZK if you build with the included ZK code.
It simply means the client code we use is for the version we bundle.
Running a plain configure still allows you to connect to an existing ZK
cluster, you simply need to pass the appropriate --zk flag on the master,
and the appropriate --master flag on the slaves:
mesos-master --help
...
--zk=VAL ZooKeeper URL (used for leader election
amongst masters)
May be one of:
zk://host1:port1/path,host2:port2/path,...
zk://username:password@host1
:port1/path,host2:port2/path,...
file://path/to/file (where file contains
one of the above) (default: )
mesos-slave --help
...
--master=VAL May be one of:
zk://host1:port1/path,host2:port2/path,...
zk://username:password@host1
:port1/path,host2:port2/path,...
file://path/to/file (where
file contains one of the above)
Note that the existing help message doesn't quite match the one I included
here, as it currently has a bad ZK path example. We'll be fixing that
message soon.
That being said, you should be able to build with your own ZooKeeper
library, I just didn't have any quick hunches myself as to why this wasn't
working out for you.
