-------------------------------------
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:

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!)
