Class RemoteSlotManager

All Implemented Interfaces:

public class RemoteSlotManager extends Object implements SlotManager
Slot manager implementation that requests slots from another job agent. The other job agent should be using the MasterSlotManager. Communication between the job agents is made on the remote control port on the master job agent. Make sure that the master slot manager allows connections from this host by including it's ip address in the 'agent.remotecontrol' setting.

Configuration options for this slot manager:

  • agent.slotmanager.remote.server: The host name/ip of the master job agent
  • agent.slotmanager.remote.port: The port number of the remote control port on the master job agent.
