Due to a security > fix, yarn use user's environment variables to init, and user's environment > variable usually doesn't include MapReduce related settings. So we need to > add the related config in etc/hadoop/mapred-site.xml manually. Currently the > log only tells there is an Error: > Could not find or load main class > org.apache.hadoop.mapreduce.v2.app.MRAppMaster, without suggestion on how to > solve it. I want to add the useful suggestion in log. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
