Benjamin Mahler created MESOS-431:
-------------------------------------
Summary: Port isolation / sharing in the ephemeral range.
Key: MESOS-431
URL: https://issues.apache.org/jira/browse/MESOS-431
Project: Mesos
Issue Type: Brainstorming
Reporter: Benjamin Mahler
We currently have yet to enforce the port allocations: MESOS-359
An additional issue is that we don't enforce any kind of fairness in the
ephemeral range. At twitter, this manifests in connection-heavy jobs using the
full ephemeral range. In turn, any executors we attempt to run after this point
cannot bind to an ephemeral port.
We should explore enforcement of fair-sharing of ports, not sure how this ties
into providing each executor with its own networking stack. This may be
unnecessary in the long term depending on how we implement network isolation.
