> Currently the order of events in MiniYarnCluster is nondeterministic as the events are triggered by scheduled timers. This makes it difficult to write tests since some erroneous scenarios are triggered only after some particular sequence of events. An example is the bug in YARN-779 where without this control over events, writing a deterministic unit test is not possible. We should modify the source to allow both manual invocation of events as well as via existing periodic timers. MiniYarnCluster can then expose such methods for more control over events ordering.
