5)重启namenode
sudo -u hdfs /usr/lib/hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf/ stop namenode
sudo -u hdfs /usr/lib/hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf/ start namenode
重启jobtracker，在主节点（jobtracker）执行：
sudo -u mapred /usr/lib/hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf/ stop jobtracker
sudo -u mapred /usr/lib/hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf/ start jobtracker
重启动datanode
sudo -u hdfs /usr/lib/Hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf/ start datanode
