Benjamin Mahler created MESOS-659:
-------------------------------------
Summary: The Master incorrectly sends a "Framework failed over"
message when the scheduler driver retries an initial failover re-registration.
Key: MESOS-659
URL: https://issues.apache.org/jira/browse/MESOS-659
Project: Mesos
Issue Type: Bug
Reporter: Benjamin Mahler
Assignee: Benjamin Mahler
This bug can cause unnecessary additional failovers, if say, the master is
delayed processing a re-registration attempt from a scheduler.
// Replace the scheduler for a framework with a new process ID, in the
// event of a scheduler failover.
void Master::failoverFramework(Framework* framework, const UPID& newPid)
{
const UPID& oldPid = framework->pid;
/** NEED TO GUARD AGAINST newPid == oldPid FOR RETRIES! */
{
FrameworkErrorMessage message;
message.set_message("Framework failed over");
send(oldPid, message);
}
...
}
Sending the FrameworkErrorMessage here always is incorrect, we should not be
sending it when the scheduler driver is simply re-trying the initial failover
re-registration.
