Sqoop commands are case- sensitive of table names and user names.
By specifying the above two values in UPPER case, it will resolve the issue.
In case, the source table is created under different user namespace,then table name should be like USERNAME.TABLENAME as shown below
sqoop import
--connect jdbc:oracle:thin:@intellipaat.testing.com/INTELLIPAAT
--username SQOOP
--password sqoop
--table COMPANY.EMPLOYEES
