> Key: MESOS-530
> URL: https://issues.apache.org/jira/browse/MESOS-530
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Vinod Kone
> Assignee: Vinod Kone
> Fix For: 0.13.0

>
> We have seen this in production at Twitter
> Timeline of events:
> 06/26 06:46: Slave host rebooted
> 06/26 06:46.54: Slave registered (201305082239-1864771594-5050-8729-594) with
> master. But slave never got the ACK. Presumably there were network partition
> issues.
> 06/26 06:47.21: Slave disconnected from the master and the master removed the
> slave.
> 06/26 06:47.21: Immediately after, the master registered the slave with a new
> id (201305082239-1864771594-5050-8729-609).
> But the slave only received the old id
> (201305082239-1864771594-5050-8729-594)!!! So there is a mismatch between the
> slave id known to the master and the slave!
> Currently the slave silently ignores a (re-)registration message from the
> master if it is already (re-)registered. This was originally designed to
> ignore duplicate (re-)registered messages sent by the master. But clearly it
> doesn't catch the above edge case.
