Avro's isElementType() change breaks the reading of some parquet(1.8.1) files

When using the Avro schema below to write a parquet(1.8.1) file and then read back by using parquet 1.10.1 without passing any schema, the reading throws an exception "XXX is not a group" . Reading through parquet 1.8.1 is fine. 

           {

              "name": "phones",

              "type": [

                "null",

                {

                  "type": "array",

                  "items": {

                    "type": "record",

                    "name": "phones_items",

                    "fields": [

                      

{                         "name": "phone_number",                         "type": [                           "null",                           "string"                         ],                         "default": null                       }

                    ]

                  }

                }

              ],

              "default": null

            }

The code to read is as below 

     val reader = AvroParquetReader._builder_[SomeRecordType](parquetPath).withConf(**new**   Configuration).build()

    reader.read()

PARQUET-651 changed the method isElementType() by relying on Avro's checkReaderWriterCompatibility() to check the compatibility. However, checkReaderWriterCompatibility() consider the ParquetSchema and the AvroSchema(converted from File schema) as not compatible(the name in avro schema is ‘phones_items’, but the name is ‘array’ in Parquet schema, hence not compatible) . Hence return false and caused the “phone_number” field in the above schema to be considered as group type which is not true. Then the exception throws as .asGroupType(). 

I didn’t try writing via parquet 1.10.1 would reproduce the same problem or not. But it could because the translation of Avro schema to Parquet schema is not changed(didn’t verify yet). 

 I hesitate to revert PARQUET-651 because it solved several problems. I would like to hear the community's thoughts on it.

提供された Avro スキーマ、parquet 1.8.1 の出力、parquet 1.10.1、および AvroParquetReader を使って失敗を再現し、その後、PARQUET-651 で変更された isElementType() のロジックと互換性チェックを調査します。この配列形式のレコードスキーマを持つ古いファイルを “not a group” 例外なしで読み取れるようになり、リポジトリに回帰テストがある場合はその動作が回帰テストでカバーされていれば完了です。
