This information is missing, such that we worked around to considered the container with ID "xxxx_01" as the AM container. Unfortunately, this is neither necessary or sufficient condition. We need to have a way to determine if a container is an AM container on NM. We can add flag to the container object or create an API to do the judgement. Perhaps the distributed AM information may also be useful to YARN-2877. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
