Reuben Kuhnert reassigned PARQUET-388:
--------------------------------------
Assignee: Reuben Kuhnert
> ProtoRecordConverter might wrongly cast a Message.Builder to Message
> --------------------------------------------------------------------
>
> Key: PARQUET-388
> URL: https://issues.apache.org/jira/browse/PARQUET-388
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Reporter: Wu Xiang
> Assignee: Reuben Kuhnert
>
> ProtoRecordConverter returns current record as follows:
> public T getCurrentRecord() {
> if (buildBefore) {
> return (T) this.reusedBuilder.build();
> } else {
> return (T) this.reusedBuilder;
> }
> }
> However this might fail if T is subclass of Message and buildBefore == false,
> since it's actually casting a Message.Builder instance to Message type.
