Input terminal: the sudo Start-Service MySQL open mysql.
Free secret landing configuration: RM -rf ~ / .ssh / enter ssh-keygen knock three Enter

1. introduced into the hdfs
In the terminal type: start-dfs.sh
Enter jps view the process:
After entering: Start-yarn.shk open yarn
Enter jps View
After entering: Sqoop Import --connect JDBC: MySQL: // localhost: 3306 / lydsj --username the root -P---table tbl_gender --target the dir / MySQL / Output - M. 1 to import data into the database hdfs directory, the process to enter the database password (my 000000). We need to wait for some time.
Use hadoop fs -cat / mysql / output / part-m-00000 results View introduced
2. introduced into the hbase
在开启了hdfs和yarn的情况下，输入：zkServer.sh start开启Zookeeper，之后输入start-hbase.sh开启hbase。
输入jps查看进程：
在终端中输入hbase shell
输入：create 'tbl_dim','info'创建一张表
输入quit退出hbase shell
然后输入命令sqoop import -m 1 --connect jdbc:mysql://localhost:3306/lydsj --username root --password 000000 --table tbl_dimensioncat --hbase-table tbl_dim --columns DIMCATID,DIMENSIONNAME,MEMO --column-family info --hbase-row-key DIMCATID
将数据导入到Hbase中
再在终端输入habse shell然后在shell中输入scan 'tbl_dim'查看表中的内容
结束。
