Description

In the early days of the development we've added new feature to the JDBC connector that enabled user to specify custom query to insert the data - similarly as user can specify custom query to select data. I see several problems with the feature:

• It's actually not working at all right now because we're not able to generate schema from the custom query.
• It doesn't allow us to do any batching as we're doing in Sqoop 1 when we're putting several rows into the same query which will hurt performance.
• I did not see any real request for this feature from users

Hence I would like to propose dropping this unfinished/non-working feature all together. Any thoughts?
