Vinod Kone created MESOS-310:
--------------------------------
Summary: cgroups isolation module should not block on fetching
executors
Key: MESOS-310
URL: https://issues.apache.org/jira/browse/MESOS-310
Project: Mesos
Issue Type: Bug
Reporter: Vinod Kone
With the latest refactor in isolation module, fetching of an executor is done
by the isolation module.
If for some reason the fetch blocks (for eg: HDFS issue), all the other
messages to the isolation module are enqueued. This is problematic because,
when a new task arrives, the slave currently dispatches resourcesChanged() call
to the isolation module and immediately sends the task to the executor.
Subsequently, the executor might be running a task without the isolation module
updating the cgroups!
