--------------------------------------
We also ran into this issue with latest master parquet build:

> Key: PARQUET-1711
> URL: https://issues.apache.org/jira/browse/PARQUET-1711
> Project: Parquet
> Issue Type: Bug
> Affects Versions: 1.10.1
> Reporter: Lawrence He
> Priority: Major
>
> Writing following protobuf message as parquet file is not possible:
> {code:java}
> syntax = "proto3";
> import "google/protobuf/struct.proto";
> package test;
> option java_outer_classname = "CustomMessage";
> message TestMessage {
> map<string, google.protobuf.ListValue> data = 1;
> } {code}
> Protobuf introduced "well known json type" such like [ListValue|https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#listvalue] to work around json schema conversion.
> However writing above messages traps parquet writer into an infinite loop due to the "general type" support in protobuf. Current implementation will keep referencing 6 possible types defined in protobuf (null, bool, number, string, struct, list) and entering infinite loop when referencing "struct".
