Hi,

I don't understand this part of your answer: "read the other as a
side-input directly by creating a client.".

If I consider both inputs through the InputFormat, this means that a job
will contain both input path in its configuration, and this is enough to
work. So, what is the "other"? Is is the second input? Can you please
explain what you have meant?
