@elmismo999

Sqoop uses Mapreduce so make sure it's running and YARN then secondly you first validate that the database and table exist, follow the below steps

# mysql -u root -p[root_password]

mysql>show databases;
If the sqoop database exists then run

mysql> use sqoop;

mysql> show tables;

This MUST show the table result if it doesn't then your export cannot work and export command I don't see the MySQL database port default 3306 and the root password place holder -P or simple -p[root_password]
# sqoop import --connect jdbc:mysql://127.0.0.1:3306/sqoop --username root -P --table result --target-dir /user/results10/

Can you confirm the above and revert
