Chainable computations for tault tolerance
------------------------------------------
Key: HAMA-503
URL: https://issues.apache.org/jira/browse/HAMA-503
Project: Hama
Issue Type: Improvement
Components: bsp
Affects Versions: 0.4.0
Reporter: Thomas Jungblut
Fix For: 0.5.0
refactor bsp() in allowing checkpointed messages to be recovered.
ChiaHung Lin had a fancy idea in chaining superstep class to make the whole
recovering more convenient and less error prone, or at least possible.
A user does not define a BSP anymore, instead he defines a single superstep
inside of a computation class. A user is able to chain these in a specific
ordering. After each of this computation the framework calls sync() and
exchanges the messages.
