> Key: MESOS-3775
> URL: https://issues.apache.org/jira/browse/MESOS-3775
> Project: Mesos
> Issue Type: Improvement
> Components: technical debt, test
> Reporter: Alexander Rukletsov
> Assignee: Shuai Lin

>
> The {{MasterAllocatorTest.SlaveLost}} takes more that {{5s}} to complete. A
> brief look into the code hints that the stopped agent does not quit
> immediately (and hence its resources are not released by the allocator)
> because [it waits for the executor to
> terminate|https://github.com/apache/mesos/blob/master/src/tests/master_allocator_tests.cpp#L717].
> {{5s}} timeout comes from {{EXECUTOR_SHUTDOWN_GRACE_PERIOD}} agent constant.
> Possible solutions:
> * Do not wait until the stopped agent quits (can be flaky, needs deeper
> analysis).
> * Decrease the agent's {{executor_shutdown_grace_period}} flag.
> * Terminate the executor faster (this may require some refactoring since the
> executor driver is created in the {{TestContainerizer}} and we do not have
> direct access to it.
