Vinod Kone created MESOS-623:
--------------------------------
Summary: Cluster::slaves::shutdown() doesn't call shutdown the
slaves
Key: MESOS-623
URL: https://issues.apache.org/jira/browse/MESOS-623
Project: Mesos
Issue Type: Bug
Reporter: Vinod Kone
Fix For: 0.14.0
Currently, it simply terminates the slaves without calling shutdown. While the
former doesn't wait for executors to shutdown, the latter waits for the
executors to be terminated.
While fixing this in 'Cluster' is simple, there are quite a few tests that are
going to break with this change.
--> MockExecutor's shutdown is a no-op, so the slave never gets an
executorTerminated() until it times out and sends a kill via the isolator. This
will increase the test duration by 5s!
--> Some tests resume the Clock after Cluster::shutdown() which means the slave
never times out and sends a kill via the isolator.
--> At least one test (AllocatorTest.FrameworkExited) uses the same executor
for 2 different frameworks, which breaks the isolator when killing the
executors twice.
