Class JoinSeedNodeProcess
java.lang.Object
akka.cluster.JoinSeedNodeProcess
- All Implemented Interfaces:
- Actor, ActorLogging
public final class JoinSeedNodeProcess
- extends java.lang.Object
- implements Actor, ActorLogging
INTERNAL API.
Sends InitJoin to all seed nodes (except itself) and expect
InitJoinAck reply back. The seed node that replied first
will be used, joined to. InitJoinAck replies received after the
first one are ignored.
Retries if no InitJoinAck replies are received within the
SeedNodeTimeout.
When at least one reply has been received it stops itself after
an idle SeedNodeTimeout.
The seed nodes can be started in any order, but they will not be "active",
until they have been able to join another seed node (seed1).
They will retry the join procedure.
So one possible startup scenario is:
1. seed2 started, but doesn't get any ack from seed1 or seed3
2. seed3 started, doesn't get any ack from seed1 or seed3 (seed2 doesn't reply)
3. seed1 is started and joins itself
4. seed2 retries the join procedure and gets an ack from seed1, and then joins to seed1
5. seed3 retries the join procedure and gets acks from seed2 first, and then joins to seed2
