Description

I see the odd exception from the Python side:

ArrowException: NotImplemented: list<: uint8>

The schema is:

$ debug/parquet-dump-schema ~/Downloads/nation.impala.parquet 
required group schema {
  optional int32 n_nationkey
  optional byte_array n_name
  optional int32 n_regionkey
  optional byte_array n_comment
}

This may have been introduced by https://github.com/apache/parquet-cpp/commit/8487142f6d5a60d12e3068ac226b2b5dfe178350
