Subject [jira] [Commented] (HAMA-411) Support checkpoint based on HDFS
Date Thu, 07 Jul 2011 05:39:16 GMT


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 first. This
issue is going to put messages to disk.

But I first let Edward refactor the task management in
Afterwards we'll see where to implement these things.
