How to secure sqoop data transfer channel

avatar

Is there any way to secure the data transfer between the source and datanodes while using Sqoop?

I know we can use Kerberos for authentication but not sure if we have any way to secure the data transfer. Please advise.

This looks more like authentication solution than securing the data channels to eliminate the risk of having your data transfer in clear text. Am i missing anything here?

You could use useSSL=true and requireSSL flag sqoop as mentioned below.

Have tried with useSSL=true and requireSSL in my Sqoop command and its got executed successfully. But i could not see anywhere in the LOG where it has been mentioned about SSL connection.

Is there any way i could verify the confirm the SSL implementation in my sqoop command ? Please suggest
