--------------------------------------

             Summary: ComplexWriterImpl.setValueCount() doesn't set the value count of its "root" container
                 Key: ARROW-329
                 URL: https://issues.apache.org/jira/browse/ARROW-329
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java - Vectors
            Reporter: Deneche A. Hakim
            Assignee: Deneche A. Hakim


The following code:
{code}
    MapVector vector = new MapVector(name, allocator, null);
    ComplexWriterImpl mapWriter = new ComplexWriterImpl("colMap", vector);
    BaseWriter.MapWriter mapWr = mapWriter.rootAsMap();
    // write into the map vector
    …
    mapWriter.setValueCount(5);
{code}

is expected to set the value count of _vector_ to 5, but it doesn't
