[jira] [Issue Comment Edited] (HAMA-440) Integrity of checkpointed data

    [ https://issues.apache.org/jira/browse/HAMA-440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13226775#comment-13226775 ]

------------------------------------------------------------

This issue concerns if we have a complete snapshot of all tasks (involved in a job) per superstep so that in the later stage when requiring to do recovery, master can find the latest snapshot for bsp tasks.

> Data must be consistent, so we may check it for integrity before rolling back in a superstep.
