[jira] [Commented] (YARN-5241) FairScheduler fails to release
container it is just allocated
[ https://issues.apache.org/jira/browse/YARN-5241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15330540#comment-15330540 ]
Karthik Kambatla commented on YARN-5241:
----------------------------------------
Thanks for updating the patch, [~chenfolin]. I understand the issue now and the approach in the patch seems reasonable.
For improved readability, can we do the following:
# Set needRelease if it either newlyAllocatedContainers or liveContainers has it.
# Also, would be nice to remove from both collections at the same time. The code would likely look like:
{code}
boolean needRelease = newlyAllocatedContainers.contains(rmContainer)
|| liveContainers.containsKey(rmContainer.getContainerId());
newlyAllocatedContainers.remove(rmContainer);
liveContainers.remove(rmContainer.getContainerId());
{code}
# The indentation of the if check for whether debug logging is enabled is not proper. Mind updating that?

> NodeManager heartbeat event NODE_UPDATE and ApplicationMaster allocate operate may cause repeat container completed, it can lead something wrong.
> Node releaseContainer can pervent repeat release operate:
> like:
> public synchronized void releaseContainer(Container container) {
> if (!isValidContainer(container.getId())) {
> LOG.error("Invalid container released " + container);
> return;
> }
> FSAppAttempt containerCompleted did not prevent repeat container completed operate.
> Detail logs at attach file.
