Summary: Improve TestManualCheckpoint
Key: GIRAPH-270
URL: https://issues.apache.org/jira/browse/GIRAPH-270
Project: Giraph
Issue Type: Bug
Reporter: Alessandro Presta
Assignee: Aravind Anbudurai
A good test case for checkpointing is important as we experiment, for example,
with storing messages separately to enable out-of-core messaging.
There are two problems with TestManualCheckpoint:
- It's only checking that the sum of vertex ids is invariant. This doesn't
guarantee that we're correctly restoring vertex values, edges, and messages.
- The "restarted job" seems to actually start from scratch, and overwrite the
previous job's checkpoints. What we are expecting, instead, is the restarted
job to load the latest checkpoint and start from there.
