[jira] [Commented] (REEF-1406) Fix TestEvaluatorWithActiveContextImmediatePoison failures with unattached context

["Markus Weimer (JIRA)" <ji...@apache.org>]

Markus Weimer commented on REEF-1406:
-------------------------------------

This is related to [REEF-1403], in that its root cause seems to be improper locking in the Evaluator as well.

> {{TestEvaluatorWithActiveContextImmediatePoison}} test fails transiently, typically in in AppVeyor. From the logs of [~markus.weimer]'s repro, the evaluator fails (correctly) but doesn't have failed context attached (incorrectly, we expect to have a context attached).
> Most likely the failure happens too soon (with 0 msec delay after {{ContextConfiguration.OnContextStart}} event) before the information about the context has time to propagate to evaluator. We need to check whether this can be fixed in REEF code, or only in test code.
