Anand Mazumdar updated MESOS-4255:
----------------------------------
Shepherd: Vinod Kone
Sprint: Mesosphere Sprint 26
> Add mechanism for testing recovery of HTTP based executors
> ----------------------------------------------------------
>
> Key: MESOS-4255
> URL: https://issues.apache.org/jira/browse/MESOS-4255
> Project: Mesos
> Issue Type: Bug
> Reporter: Anand Mazumdar
> Assignee: Anand Mazumdar
> Labels: mesosphere
>
> Currently, the slave process generates a process ID every time it is
> initialized via {{process::ID::generate}} function call. This is a problem
> for testing HTTP executors as it can't retry if there is a disconnection
> after an agent restart since the prefix is incremented.
> {code}
> Agent PID before:
> slave(1)@127.0.0.1:43915
> Agent PID after restart:
> slave(2)@127.0.0.1:43915
> {code}
> There are a couple of ways to fix this:
> - Add a constructor to {{Slave}} exclusively for testing that passes on a
> fixed {{ID}} instead of relying on {{ID::generate}}.
> - Currently we delegate to slave(1)@ i.e. (1) when nothing is specified as
> the URL in libprocess i.e. {{127.0.0.1:43915/api/v1/executor}} would delegate
> to {{slave(1)@127.0.0.1:43915/api/v1/executor}}. Instead of defaulting to
> (1), we can default to the last known active ID.
