Github user majakabiljo commented on the issue:
https://github.com/apache/giraph/pull/30
Can we get rid of getHostnamePartitionId() to avoid incorrectly using it in
the future? I see various other places where taskPartition is used for
identifier, do any of them need to be updated too?
> Resuming from checkpoint doesn't work

> Key: GIRAPH-1139
> URL: https://issues.apache.org/jira/browse/GIRAPH-1139
> Project: Giraph
> Issue Type: Bug
> Components: bsp
> Affects Versions: 1.2.0
> Reporter: Nic Eggert
>
> I ran into a couple of issues when trying to get Giraph to resume from
> checkpoints (using mapreduce.max.attempts rather than GiraphJobRetryChecker).
> * If we just wrote a checkpoint, the master expects the workers to checkpoint
> again, while the workers (correctly) clear the checkpointing flag.
> * When workers restart, they take their task id from the partition number,
> which stays the same across multiple attempts. This gets transferred to the
> Netty clientId, and the server starts ignoring messages from restarted
> workers because it thinks it processed them already.
> I believe I've fixed these issues. I'll send a GitHub PR shortly.
