An initial stab at an RDD for Variant Store.
@cassiedoll, unless I'm missing something, it looks fairly straightforward.  Below are my steps:

1) I went to the following website:

https://developers.google.com/api-client-library/java/apis/genomics/v1beta

2) Then I clicked on the following to download the jar and sources:

https://developers.google.com/resources/api-libraries/download/genomics/v1beta/java

3) Then I unpacked the following file, which produced a genomics folder with more files and subfolders:

`google-api-services-genomics-v1beta-rev22-java-1.19.0.zip`

4) Then I unpacked the following file, which was in the root of the genomics folder:

`google-api-services-genomics-v1beta-rev22-1.19.0-sources.jar`

5) Then I went to the following folder:

`com\google\api\services\genomics\model`

6) I then opened the files `Call.java` and `Variant.java`, and updated them as follows:

`import java.io.Serializable;`

`public final class Call extends com.google.api.client.json.GenericJson implements Serializable {`

`public final class Variant extends com.google.api.client.json.GenericJson implements Serializable {`

Then the only thing left would be to compile and to generate an updated jar file that contains the serializable classes.

Is this along the lines of what you were thinking?
