Suraj Menon updated HAMA-551:
-----------------------------
Comment: was deleted
(was: Reasons for HAMA-557 requirements are as followed in descending order of
their importance:
1. Make checkpointing asynchronous. Would reduce the delay during sync. The
checkpoint function you mentioned would then be optional and could be used only
if there is a need to sync with the ending of checkpointing process for that
superstep. The design would be similar to how spilling is implemented in Hadoop.
2. Update BSPMaster with the checkpointing status of each task with superstep
count and checkpoint file. (We can live without this as we have a convention
for naming checkpointing files)
3. Tighter integration of Checkpointer with MessageManager.
I would be putting up a design document for HAMA-551. )
