James DeFelice created MESOS-8169: ------------------------------------- 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: {code} 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!) /cc [~neilc] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
