starting yarn daemons

starting resourcemanager, logging to /Users/hadoop/hadoop-2.7.3/logs/yarn-hadoop-resourcemanager-MacBook-Pro-2.local.out

nohup: can't detach from console: Inappropriate ioctl for device

localhost: starting nodemanager, logging to /Users/hadoop/hadoop-2.7.3/logs/yarn-hadoop-nodemanager-MacBook-Pro-2.local.out

Answer 1

我修改了脚本 $HADOOP_HOME/sbin/yarn-daemon.sh ，即：删除了 nohup

来自：

nohup nice -n $YARN_NICENESS "$HADOOP_YARN_HOME"/bin/yarn --config $YARN_CONF_DIR $command "$@" > "$log" 2>&1 /null &

到

nice -n $YARN_NICENESS "$HADOOP_YARN_HOME"/bin/yarn --config $YARN_CONF_DIR $command "$@" > "$log" 2>&1 /null &

现在我可以启动资源管理器了
