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)
