Download and copy the commons-lang-2.6.jar to /usr/local/sqoop/lib folder and import will work fine.

I am using Hadoop - 3.2.0 and Sqoop 1.4.7

Try the below command: 

sqoop import --connect jdbc:mysql://localhost:3306/sqoopdb --driver com.mysql.jdbc.Driver --username sqoop -P --table employee --m 1

Also make sure you have granted the access for this database using 

% mysql -u root -p 
Enter password:
mysql> GRANT ALL PRIVILEGES ON sqoopdb.* TO ''@'localhost';
Query OK, 0 rows affected (0.00 sec)
mysql> quit;
Bye
