Thomas Jungblut updated HAMA-445:
---------------------------------

    Description: 
We should extend the BSPJob to let the user set the checkpoint intervals.

bq.  job.setCheckpointInterval(5);

This method should put the parameter into the configuration of the job with a meaningful key, e.G. "bsp.checkpoint.interval".

In the BSPPeerImpl we should check if this interval has been reached and make the checkpointing accordingly.
Checkpointing gets called in BSPPeerImpl#sync(), there is already a condition which checks if checkpointing is enabled.

Plus points:
If you can provide an additional method in BSPJob that let's the user enable or disable checkpointing. Hint: Configuration key is: "bsp.checkpoint.enabled".

  was:Currently it works? It would be nice if it is configurable for a user.
