    <p>I get the following error when I connect to mysql on one cluster (<code>aaaaaa1</code>) and sqooop on a different server (<code>aaaaaa2</code>), despite creating a table in mySql with full permissions granted to the other cluster.</p> <p>Please help me to determine what is the cause of this issue. Thanks!</p> <pre><code>**$sqoop import --connect jdbc:mysql://(address of mysql):11000/sqoopdemo --table widgets** 12/10/12 10:42:23 INFO manager.MySQLManager: Preparing to use a MySQL streaming resultset. 12/10/12 10:42:23 INFO tool.CodeGenTool: Beginning code generation 12/10/12 10:42:23 ERROR manager.SqlManager: Error executing statement: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
