ChiaHung Lin commented on HAMA-431:
-----------------------------------
Indeed, 3 checkpointer processes were one solution implemented previously. It
was just that having 3 processes doing the same things seems too redundant.
Thus the implementation was shifted because the first goal is to ensure bsp
task working smoothly. We can discuss this in other threads/ issues if needed.
And yes at the moment the checkpointed data is written to hdfs with
jobid/supersteps/taskid so that data recovery would be possible. : )
