Subject [jira] [Commented] (S4-113) Recovery tests fail sometimes
Date Wed, 16 Jan 2013 17:58:13 GMT


Matthieu Morel commented on S4-113:

Thanks for pointing this out! In some of the checkpointing tests, we rely on Zookeeper notifications.
Unfortunately, (my bad), these notifications can be received before file checkpoints are completed
(especially with slow disks).

Adding pauses is far from ideal, though apart from intercepting the checkpoint notification
(and thus modifying the classes we are testing), or using java 7's improved file API, it might
be the best solution for the moment. So I'll do that, but any other suggestion is welcome.
