But if multiple versions of the plugin are present on the classpath, there is no control over which version actually gets loaded. Or if there are any conflicts between the dependencies introduced by the auxiliary service and the NM itself, they can break the NM, the auxiliary service, or both. > The solution could be: to instantiate aux services using a classloader that is different from the system classloader. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
