Zhijie Shen created YARN-966:
--------------------------------
Summary: The thread of ContainerLaunch#call will fail without any
signal if getLocalizedResources() is called when the container is not at
LOCALIZED
Key: YARN-966
URL: https://issues.apache.org/jira/browse/YARN-966
Project: Hadoop YARN
Issue Type: Bug
Reporter: Zhijie Shen
Assignee: Zhijie Shen
In ContainerImpl.getLocalizedResources(), there's:
{code}
assert ContainerState.LOCALIZED == getContainerState(); // TODO: FIXME!!
{code}
ContainerImpl.getLocalizedResources() is called in ContainerLaunch.call(),
which is scheduled on a separate thread. If the container is not at LOCALIZED
(e.g. it is at KILLING, see YARN-906), an AssertError will be thrown and fails
the thread without notifying NM. Therefore, the container cannot receive more
events, which are supposed to be sent from ContainerLaunch.call(), and move
towards completion.
