Description

Per the parquet.thift spec, for primitive nodes the num_children schema
attibute should remain unset. This is implemeted correctly in parquet-mr
see [1]. However currently parquet-cpp does set the num_children
attribute to 0 if it is a primitive node. This pull requests fixes this
issue and the tests that were relying on this behavior
