Thomas Jungblut commented on HAMA-431:
--------------------------------------
Thanks for the state machine. Looks good.
A fault scenario would be great, too.
I would create the statemachine for fault cases in the first implementation,
but with no action triggered. So we can easily add this later.
Let's assemble what daemons we have to launch from the application master:
- n BSP Tasks
- a checkpointer per host? [1]
- the sync daemon [2]
[1] I see a real problem here, maybe we have to integrate this into a running
task / BSPPeer.
[2] Based on where YARN is scheduling the container it might check for a free
port. How do we get the hostname:port of this maschine then?
