启动Hadoop

1.到Hadoop安装目录下输入命令

sbin/start-all.sh

[root@localhost hadoop-2.7.1]# sbin/start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [localhost]
root@localhost's password: 
localhost: starting namenode, logging to /usr/local/hadoop-2.7.1/logs/hadoop-root-namenode-localhost.localdomain.out
root@localhost's password: 
localhost: starting datanode, logging to /usr/local/hadoop-2.7.1/logs/hadoop-root-datanode-localhost.localdomain.out
Starting secondary namenodes [0.0.0.0]
root@0.0.0.0's password: 
0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop-2.7.1/logs/hadoop-root-secondarynamenode-localhost.localdomain.out
starting yarn daemons
starting resourcemanager, logging to /usr/local/hadoop-2.7.1/logs/yarn-root-resourcemanager-localhost.localdomain.out
root@localhost's password: 
localhost: starting nodemanager, logging to /usr/local/hadoop-2.7.1/logs/yarn-root-nodemanager-localhost.localdomain.out

2.jps查看，在此过程中需要四次输入password

[root@localhost hadoop-2.7.1]# jps
7493 NameNode
8261 ResourceManager
8022 SecondaryNameNode
8809 Jps
8620 NodeManager
7726 DataNode

启动Hbase

1. 到Hbase安装目录下输入命令

bin/start-hbase.sh

[root@localhost opt]# cd hbase-2.1.0/
[root@localhost hbase-2.1.0]# bin/start-hbase.sh 
root@localhost's password: 
localhost: running zookeeper, logging to /opt/hbase-2.1.0/bin/../logs/hbase-root-zookeeper-localhost.localdomain.out

: running regionserver, logging to /opt/hbase-2.1.0/logs/hbase-root-regionserver-localhost.localdomain.out

2.jps查看

[root@localhost hbase-2.1.0]# jps
