Good evening!   Today I got access to Cloudera Live/GoGrid and started to work through the tutorial starting at the very beginning -  using Sqoop to import a MySQL DB.   I copied this command from the tutorial guide:   sqoop import-all-tables \ -m 12 \ --connect jdbc:mysql://i7d61-cldramaster-01:3306/retail_db \ --username=retail_dba \ --password=cloudera \ --compression-codec=snappy \ --as-avrodatafile \ --warehouse-dir=/user/hive/warehouse   However, I receive multiple errors relating to a 'Communications link failure, here is a snippet:   14/10/28 18:35:14 INFO sqoop.Sqoop: Running Sqoop version: 1.4.4-cdh5.1.0 14/10/28 18:35:14 WARN tool.BaseSqoopTool: Setting your password on the command-line is insecure. Consider using -P instead. 14/10/28 18:35:14 INFO manager.MySQLManager: Preparing to use a MySQL streaming resultset. 14/10/28 18:35:14 ERROR manager.CatalogQueryManager: Failed to list tables com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure   I understand from research this typically relates to connectivity issues, but as I am using a self contained environment designed for this tutorial I would not have expected to have these types of issues. 🙂   Any guidence would be appreciated!    Thanks.     ...
