This makes me a bit nervous. There are \-jhyde classified JARs pulled in from
random repos here. [~julianhyde], are these part of the SNAPSHOT build for
calcite, or is Samza expected to depend on the conjars repository even after
Calcite is released?

> Per discussion with [~criccomini] and [~milinda], we agreed that it seems to
> be a good idea to define a common representation of relational algebra on top
> of the operators defined in the operator layer (see SAMZA-482), which can be
> the common base that we can use to generate the description/configuration of
> a Samza job.
> This common layer can also be used by DSL-like language parser as a result of
> parsing a DSL program.
> Some additional requirements needed in addition to pure relational algebra:
> 1) the common representation should include window operators and stream
> operators (i.e. IStream/DStream/RStream)
> 2) the common representation should include description on parallelism of the
> jobs (i.e. how many partitions the resultant Samza job will use)
