Thomas Jungblut commented on HAMA-431:
--------------------------------------
Checked in first version of BSPAppMaster and the job stuff
(event/implementation etc).
We need to rethink our states and transitions, but I think we can barely cut
them down to Setup->Compute->Cleanup.
A more sophisticated way would be to split the compute state into the
supersteps. So each supersteps gets handled by a statetransition. But that
could introduce a lot of overhead, but it seems to be cleaner than the handling
of zookeeper. E.G. we can wait until every task has reached this transition
with a cyclic barrier. Just like in the LocalBSPRunner.
And we need to write the event dispatchers for them.
My next goal would be to rewrite the BSPJobImpl class for our needs e.G. remove
the map and reduce tasks counter and extract an interface.
