Jian He commented on YARN-2821:
-------------------------------
thanks Varun ! looks good overall.
test case - for below, we need to test that if AM receives any unknown
completed container, the numCompletedContainers still equals to the
numTotalContainers
{code}
// ignore containers we know nothing about - probably from a previous
// attempt
if (!launchedContainers.contains(containerStatus.getContainerId())) {
LOG.info("Ignoring completed status of "
+ containerStatus.getContainerId()
+ "; unknown container(probably launched by previous attempt)");
continue;
}
{code}
> Distributed shell app master becomes unresponsive sometimes
