Edward J. Yoon commented on HAMA-974:
-------------------------------------
Isn't HAMA-881 already addressed? I tested AsyncRcvdMsgCheckpointImpl, and it
works fine.
The problem is the last-checkpoint variables states. I think providing some
custom checkpoint function is best. For example, we can add checkpointState()
method to BSPInterface.
{code}
public setup() { }
public bsp() {
// your program
}
public checkpointState() {
// define variables to be checkpointed
}
public close() { }
{code}

> aggregators, assigned vertices and its statuses must be checkpointed together.
