Description

When outputting a TableRow that has a Null value for a key, a Null Pointer Exception is thrown. In the Dataflow SDK (1.9) this case is handled by outputting NULL for that field.

I would expect the same behavior from the Beam SDK - since otherwise there is always a lot of Null checking necessary in the user code. (Especially when there are nested fields.)
