Subject Re: Guidelines for writing SPARK packages

Thanks David.

I am looking at extending the SparkSQL library with a custom 
package...hence was looking at more from details on any specific classes 
to be extended or implement (with) to achieve the redirect of calls to my 
module (when using .format).

If you have any info on these lines do share with me...else debugging 
through would be the way :-)

Thanking You

Praveen Devarao

Hi Praveen,

The basic requirements for releasing a Spark package on are as follows:

1. The package content must be hosted by GitHub in a public repo under
the owner's account.
2. The repo name must match the package name.
3. The master branch of the repo must contain "" and "LICENSE".

Per the doc on site an example package that meets
those requirements can be found at My own recently released
SAMBA package also meets these requirements:

As you can see there is nothing in this list of requirements that
demands the implementation of specific interfaces. What you'll need to
implement will depend entirely on what you want to accomplish. If you
want to register a release for your package you will also need to push
the artifacts for your package to Maven central.
