make(Map<String,Object> conf,
String supervisorId,
int supervisorPort,
IContext sharedContext,
StormMetricsRegistry metricsRegistry,
ContainerMemoryTracker containerMemoryTracker,

Factory to create the right container launcher for the config and the environment.

abstract Container |
recoverContainer(int port,
LocalAssignment assignment,
LocalState state)
Recover a container for a running process.
|
abstract Killable |
recoverContainer(String workerId,
LocalState localState)
Try to recover a container using just the worker ID.
The result is really only useful for killing the container and so is returning a Killable. |
