Hi Jarec,
              I have added a patch for the Aqoop Jira SQOOP-2801<https://issues.apache.org/jira/browse/SQOOP-2801> : Secure RDBMS password in Sqoop Metastore in a encrypted form.The review link is https://reviews.apache.org/r/42714/

Description of the work done here :

Currently Sqoop store password in the sqoop metastore in the form of plain text.While running command, sqoop job --show <job_name> , password becomes visible as plain text.Also anyone can see the password in metastore db since it is visible in a plain text.In order to provide more security, CryptoFileLoader class is extended to store password in metastore in encrypted form.Sqoop will decrypt the password during exec job.In case of show job , the password will be visible as encrypted manner.User can pass any algorithm and passphrase to encrypt the password in a similar way as it happens in case of storing password in the File.

We are using sqoop in our project and to save password in Sqoop meta store in a secured manner , we added the above changes.If you get a chance , please review the same.


Thanks,
