SQOOP error while import

Contributor

I am getting error while importing the mysql into HDFS using sqoop. But the job runs in production successfully. But in my test environment it is not working. Even mysql jar is available in the test environment.

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
