------------------------------------------
Shepherd: Niklas Quarfot Nielsen
> Configurable Ping Timeouts
> --------------------------
>
> Key: MESOS-2110
> URL: https://issues.apache.org/jira/browse/MESOS-2110
> Project: Mesos
> Issue Type: Improvement
> Components: master, slave
> Reporter: Adam B
> Assignee: Adam B
> Labels: master, network, slave, timeout
>
> After a series of ping-failures, the master considers the slave lost and
> calls shutdownSlave, requiring such a slave that reconnects to kill its tasks
> and re-register as a new slaveId. On the other side, after a similar timeout,
> the slave will consider the master lost and try to detect a new master. These
> timeouts are currently hardcoded constants (5 * 15s), which may not be
> well-suited for all scenarios.
> - Some clusters may tolerate a longer slave process restart period, and
> wouldn't want tasks to be killed upon reconnect.
> - Some clusters may have higher-latency networks (e.g. cross-datacenter, or
> for volunteer computing efforts), and would like to tolerate longer periods
> without communication.
> We should provide flags/mechanisms on the master to control its tolerance for
> non-communicative slaves, and (less importantly?) on the slave to tolerate
> missing masters.
