> Master detector should not block on zookeeper 'get' method

> Key: MESOS-351
> URL: https://issues.apache.org/jira/browse/MESOS-351
> Project: Mesos
> Issue Type: Bug
> Reporter: Vinod Kone
> Assignee: Yan Xu
> Fix For: 0.16.0
>
>
> Currently, the master detector code calls zk->get() in its detectMaster()
> method. Under the covers, we call zoo_aget(...., callback,....) and block
> till the callback is called.
> At Twitter, we encountered a situation where zk->get() got blocked because
> the callback was never called by the underlying zookeeper library. Even if a
> watch expired indicating session expired, the detector would not process it
> because it is blocked in detectMaster().
> I will add some data below.
