1.1 啟動

[root@hadp-master sbin]# ./start-all.sh 

this script is deprecated. instead use start-dfs.sh and start-yarn.sh

starting namenodes on [hadp-master]

hadp-master: starting namenode, logging to /usr/local/hadoop/hadoop-2.7.4/logs/hadoop-root-namenode-hadp-master.out

hadp-node2: starting datanode, logging to /usr/local/hadoop/hadoop-2.7.4/logs/hadoop-root-datanode-hadp-node2.out

hadp-node1: starting datanode, logging to /usr/local/hadoop/hadoop-2.7.4/logs/hadoop-root-datanode-hadp-node1.out

starting secondary namenodes [0.0.0.0]

0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/hadoop-2.7.4/logs/hadoop-root-secondarynamenode-hadp-master.out

hadp-node1: starting nodemanager, logging to /usr/local/hadoop/hadoop-2.7.4/logs/yarn-root-nodemanager-hadp-node1.out

說明:啟動所有的hadoop守護程序。包括namenode、datanode、 secondary namenode、yarn、 yarn-root-nodemanager

1.2 關閉

[root@hadp-master sbin]# ./stop-all.sh 

this script is deprecated. instead use stop-dfs.sh and stop-yarn.sh

stopping namenodes on [hadp-master]

hadp-master: stopping namenode

hadp-node2: stopping datanode

hadp-node1: stopping datanode

stopping secondary namenodes [0.0.0.0]

0.0.0.0: stopping secondarynamenode

stopping yarn daemons

stopping resourcemanager

hadp-node2: no nodemanager to stop

hadp-node1: no nodemanager to stop

no proxyserver to stop

說明:關閉所有的hadoop守護程序。包括namenode、datanode、 secondary namenode、yarn、resourcemanager

二、模組封裝啟動、關閉

2.1 啟動

[root@hadp-master sbin]# ./start-dfs.sh

starting secondary namenodes [0.0.0.0]

0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/hadoop-2.7.4/logs/hadoop-root-secondarynamenode-hadp-master.out

說明:啟動hadoop hdfs守護程序namenode、datanode、secondarynamenode

[root@hadp-master sbin]# ./start-yarn.sh 

starting yarn daemons

starting resourcemanager, logging to /usr/local/hadoop/hadoop-2.7.4/logs/yarn-root-resourcemanager-hadp-master.out

hadp-node2: starting nodemanager, logging to /usr/local/hadoop/hadoop-2.7.4/logs/yarn-root-nodemanager-hadp-node2.out

hadp-node1: starting nodemanager, logging to /usr/local/hadoop/hadoop-2.7.4/logs/yarn-root-nodemanager-hadp-node1.out

說明:啟動yarn daemons、yarn-root-resourcemanager、yarn-root-nodemanager

2.2 關閉

[root@hadp-master sbin]# ./stop-dfs.sh

stopping namenodes on [hadp-master]

hadp-master: stopping namenode

hadp-node2: stopping datanode

hadp-node1: stopping datanode

stopping secondary namenodes [0.0.0.0]

0.0.0.0: stopping secondarynamenode
