Thanks for sharing the solution! Indeed, the -- separator lets you pass the connector specific arguments into the connector itself, than sending it to Sqoop which would not recognize them.

Extra arguments must appear at the end of the command, using -- as the delimiter.". ... View more

The dfs.permissions property is a server-side (NameNode) one. It cannot be overriden by clients. If you use CM, then /etc/hadoop/conf/ is just where your client properties are. The Server-side generated properties are maintained in isolation elsewhere, which you can view for example by going to CM ->HDFS -> Instances -> NameNode -> Processes -> hdfs-site.xml. A good doc on understanding the CM approach can also be found at http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_intro_primer.html#concept_fgj_tny_jk_unique_1 ...
