There are two mistakes in the command you are executing,
1. The spelling of password is incorrect in the command.
2. There should not be a forward slash before writing the target directory name. The default path of target directory is hdfs://nameservice1/user/edureka_<your_id>/. So, you don't have to mention the complete path in the command and also the forward slash. You can directly write the directory name.
So, the correct command will be as below,
sqoop import --connect jdbc:mysql://mysqldb.edu.cloudlab.com/employee --username labuser --password edureka --table departments --target-dir TestData --m 1
