This method internally access the container's recordCount but while
building the container I don't see we are setting the RecordCount explicitly by
calling setRecordCount on it. Neither it looks like while adding valueVector
inside the container, that count is maintained. Shouldn't we set the
recordCount ?

> Project: Apache Drill
> Issue Type: Sub-task
> Components: Tools, Build & Test
> Affects Versions: 1.11.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Fix For: 1.11.0
>
>
> Operators work with individual row sets. A row set is a collection of records
> stored as column vectors. (Drill uses various terms for this concept. A
> record batch is a row set with an operator implementation wrapped around it.
> A vector container is a row set, but with much functionality left as an
> exercise for the developer. And so on.)
> To simplify tests, we need a {{TestRowSet}} concept that wraps a
> {{VectorContainer}} and provides easy ways to:
> * Define a schema for the row set.
> * Create a set of vectors that implement the schema.
> * Populate the row set with test data via code.
> * Add an SV2 to the row set.
> * Pass the row set to operator components (such as generated code blocks.)
> * Compare the results of the operation with an expected result set.
> * Dispose of the underling direct memory when work is done.
