7重启命令
7.1 hadoop
a.dfs启动停止
#start-dfs.sh
#stop-dfs.sh
亦或
# /usr/local/hadoop/sbin/start-dfs.sh
# /usr/local/hadoop/sbin/stop-dfs.sh
执行完后，jps 进程有DataNode NameNode SecondaryNameNode
端口开放9870
b.yarn启动停止
#start-yarn.sh
#stop-yarn.sh
亦或
# /usr/local/hadoop/sbin/start-yarn.sh
# /usr/local/hadoop/sbin/stop-yarn.sh
执行完后，jps 进程有ResourceManager ResourceManager
端口开放8088，8032等
注意：zookeeper必须提前启动
c.hdfs 安全模式
当前模式
hdfs dfsadmin -safemode get
开启安全模式
hdfs dfsadmin -safemode enter
关闭安全模式
hdfs dfsadmin -safemode leave
7.2 zookeeper
#/usr/local/zookeeper/bin/zkServer.sh start
#/usr/local/zookeeper/bin/zkServer.sh stop
执行完后，jps 进程有QuorumPeerMain
端口2181开放
7.3 spark
/usr/local/spark/sbin/start-all.sh
执行完后，jps 进程有Worker Master
/usr/local/spark/sbin/start-history-server.sh
执行完后，jps 进程有HistoryServer
netstat -anltup |grep 18080
注意：依次启动Hadoop的start-dfs.sh和Spark的start-all.sh后，再运行start-history-server.sh

后台启动
#nohup hive –service hiveserver2 &
Jps初见进程RunJar
10002端口为GUI的beeline界面
8开机自启动

source /etc/profile
start-all.sh
/usr/local/zookeeper/bin/zkServer.sh start
/usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties
/usr/local/spark/sbin/start-all.sh
/usr/local/spark/sbin/start-history-server.sh
nohup hive --service hiveserver2 &
