Sqoop mainly interacts data with hadoop in relational databases. As a client tool for hadoop. Can be installed on any node, I installed on the master.
1.tar -zxvf /opt/sqoop-1.4.6-cdh5.8.0.tar.gz
2. Modify environment variables
vi /etc/profile

export SQOOP_HOME=/opt/sqoop-1.4.6-cdh5.8.0
export PATH=$PATH:$SQOOP_HOME/bin
Excuting an order:
source /etc/profile
3. Verify success
[hadoop@master ~]$ sqoop list-databases --connect jdbc:mysql://master:3306/ --username root -password 123456
