Thomas Jungblut commented on HAMA-411:
--------------------------------------
I am not a fan of forcing people to override methods, so I'll think we'll
provide a default implementation which always return true.
Since checkpointing can cause overhead, some people may not need to checkpoint
in every step of the calculation.
We should consider to implement https://issues.apache.org/jira/browse/HAMA-398
first. This issue is going to put messages to disk.
But I first let Edward refactor the task management in
https://issues.apache.org/jira/browse/HAMA-410 .
Afterwards we'll see where to implement these things.
