For that specific feature we > could implement it as an additional field in the StopContainerRequest. > However that would not address other potential features like the ability for > an AM to trigger jstacks on arbitrary tasks *without* killing them. The > latter feature would be a very useful debugging tool for users who do not > have shell access to the nodes. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
