No description provided.

We have a policy of not putting binaries in the samples source. You need to provide the actual code and instructions for how to produce the binary.

[udlingal]

This is python notebook which uses a jar file. Should I put this in different place under sql-server-samples? Or should I include source code for jar file and python with binaries(this will increase zip file size) in this zip file?

[pmasl]

@udlingal we want to share the Notebook as a whole ready-to-use artifact, but please also add to your PR the source jar and python outside the zip, so that users can see the source. As soon as you do let me know and I can merge.

[udlingal]

This jar file is derivative of existing hadoopbridge connectors used for PolyBase. as it is still Microsoft propitiatory, we cannot share the code to public yet. can we place just jar files now until we can make the code public access ?

[pmasl]

Yes, as a sample this is fine for now.
