      Description

      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.
