Hello everyone. I have installed the quickstart vm and in "get started" tutorial, on the Exercise 1, when I have to launch the sqoop job:   sqoop import-all-tables \ -m 1 \ --connect jdbc:mysql://quickstart:3306/retail_db \ --username=retail_dba \ --password=cloudera \ --compression-codec=snappy \ --as-parquetfile \ --warehouse-dir=/user/hive/warehouse \ --hive-import   I received the following error. I just copied and pasted the command, I dont know what happened. Can someone help me please?   16/06/12 11:17:51 INFO sqoop.Sqoop: Running Sqoop version: 1.4.6-cdh5.5.0 16/06/12 11:17:51 WARN tool.BaseSqoopTool: Setting your password on the command-line is insecure.
