Паркет не соответствует схеме, у него все поля nulleable, а ACCOUNT_TYPE_ID_INT не должен:

[
  {
    "PrimitiveType": {
      "field_info": {
        "name": "ACCOUNT_TYPE_ID_INT",
        "repetition": "Optional",
        "id": null
      },
      "logical_type": null,
      "converted_type": null,
      "physical_type": "Int32"
    }
  },
  {
    "PrimitiveType": {
      "field_info": {
        "name": "ACCOUNT_TYPE_ID_CHAR",
        "repetition": "Optional",
        "id": null
      },
      "logical_type": "String",
      "converted_type": "Utf8",

Recreated Parquet files, created new one with all Fields marked as not null

 pqi schema ACCOUNT_TYPE.parquet
ACCOUNT_TYPE_ID_INT: int32 not null
ACCOUNT_TYPE_ID_CHAR: string not null
NAME: string not null

But I receive the same error

ydb -e grpc://c0fbrdjnem92d2p2q5jn.cluster.testing.ydb.yandex.net:2135 -d /olap-testing-vla-common2/kikimr/apkobzev/test import file parquet ACCOUNT_TYPE.parquet -p gb/ACCOUNT_TYPE
