Subject [jira] [Created] (MESOS-428) create the concept of a persistent executor
Date Sun, 07 Apr 2013 20:19:15 GMT
brian wickman created MESOS-428:

             Summary: create the concept of a persistent executor
                 Key: MESOS-428
             Project: Mesos
          Issue Type: New Feature
          Components: framework, master, slave
            Reporter: brian wickman

The idea would be to allocate (e.g. via the slave command-line or by communicating directly
to a specialized allocator) a static ExecutorInfo that would persist forever and never be
a candidate for revocation / garbage collection without manual intervention.  Its resources
could still be compressed via oversubscription and re-offered but never outright revoked.
 Ideally there would be a mechanism to authenticate a framework and allow it to securely lay
claim to a preallocated/persistent executor.

The use-case is for carving out slices of machines for stateful / persistent services, e.g.
HDFS, Kestrel, Redis, MySQL.  Rather than managing this via puppet, we'd manage them with
Mesos and leverage the Mesos toolchain and observability stack.
