-------------------------------------

             Summary: master validation incorrectly rejects slaves, buggy executorID checking
                 Key: MESOS-8169
                 URL: https://issues.apache.org/jira/browse/MESOS-8169
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: James DeFelice
            Priority: Major


proposed fix: https://github.com/apache/mesos/pull/248

I observed this in my environment, where I had two frameworks that used the same ExecutorID and then triggered a master failover. The master refuses to reregister the slave because it's not considering the owning-framework of the ExecutorID when computing ExecutorID uniqueness, and concludes (incorrectly) that there's an erroneous duplicate executor ID:

W1103 00:33:42.509891 19638 master.cpp:6008] Dropping re-registration of agent at slave(1)@10.2.0.7:5051 because it sent an invalid re-registration: Executor has a duplicate ExecutorID 'default'
{code}

(yes, "default" is probably a terrible name for an ExecutorID - that's a separate discussion!)
