Vinod Kone created MESOS-351:
--------------------------------
Summary: 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
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.
