Subject [jira] [Commented] (HAMA-411) Support checkpoint based on HDFS
Date Wed, 06 Jul 2011 07:24:16 GMT

    [ https://issues.apache.org/jira/browse/HAMA-411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13060334#comment-13060334

Thomas Jungblut commented on HAMA-411:
--------------------------------------

Correct, I think we should split this into two different tasks. 
This here is adding the function that allows the user to checkpoint and the checkpointing
itself.

The way that the BSPMaster is handle fault belongs to the other task since we are not sure
if MR2 or your phi accrual detector should be used.  (see mailing list).
But both ideas share the same checkpointing that is needed, so we can implement this now and
use it later if we strik an aggreement.
