Haibo Chen commented on MAPREDUCE-6768:
---------------------------------------
{code:java}
ContainerId t1a2contId = task1Attempt2.getAssignedContainerID();
LOG.info(t1a2contId.toString());
{code}
TaskAttempt2 may not have been assigned a container, this is why there is a
NPE. Uploading a trivial patch to fix this.
> TestRecovery.testSpeculative failed with NPE
