启动原生Hadoop集群或伪分布环境
一：启动Hadoop[*]集群或伪分布安装成功之后，通过执行./sbin/start-all.sh启动Hadoop环境
[*]通过jps命令查看当前启动进程是否正确~
# pwd
/opt/hadoop-2.6.0-cdh5.6.0
# ./sbin/start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

# jps

3030 DataNode
二：启动Hive
[*] 检查Mysql数据是否启动
# service mysqld status
mysqld is stopped
# service mysqld start
Starting mysqld:
# mysql -uroot -proot
[*] 启动Hadoop集群环境：因为Hive底层使用的是Mapreduce执行sql语句
[*] # hive
[*] 在hive中测试环境：
[*] create table test(id int);
[*] select count(*) from test;
三：启动Hbase
# cd hbase-1.0.0-cdh5.6.0/bin/
# ./start-hbase.sh
# hbase shell
