[jira] [Created] (ARROW-10840) FileMetaData does not have key_value_metadata when built from FileMetaDataBuilder

Jimmy Lu created ARROW-10840:
--------------------------------

             Summary: FileMetaData does not have key_value_metadata when built from FileMetaDataBuilder
                 Key: ARROW-10840
                 URL: https://issues.apache.org/jira/browse/ARROW-10840
             Project: Apache Arrow
          Issue Type: Bug
    Affects Versions: 2.0.0, 1.0.1, 1.0.0
            Reporter: Jimmy Lu


{{FileMetaDataImpl::key_value_metadata_}} is initialized in the constructor: https://github.com/apache/arrow/blob/apache-arrow-1.0.0/cpp/src/parquet/metadata.cc#L530

But in {{RowGroupMetaDataBuilder::Finish}}, {{FileMetaDataImpl::metadata_}} is set after the construction and we are missing the {{FileMetaDataImpl::InitKeyValueMetadata}} call here: https://github.com/apache/arrow/blob/apache-arrow-1.0.0/cpp/src/parquet/metadata.cc#L1412
