[jira] [Created] (PARQUET-1038) Key value metadata should be nullptr if not set

Phillip Cloud created PARQUET-1038:
--------------------------------------

             Summary: Key value metadata should be nullptr if not set
                 Key: PARQUET-1038
                 URL: https://issues.apache.org/jira/browse/PARQUET-1038
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-cpp
    Affects Versions: cpp-1.1.0
            Reporter: Phillip Cloud
             Fix For: cpp-1.2.0


Key value metadata is initialized with {{std::make_shared<KeyValueMetadata>()}} which returns a pointer to an empty instance of {{KeyValueMetadata}}. This breaks Arrow's deserialization of metadata because it distinguishes between {{nullptr}} and empty metadata.
