[ https://issues.apache.org/jira/browse/BEAM-12165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17321209#comment-17321209 ]
Ning Kang commented on BEAM-12165:
----------------------------------
I closed Pull Request #14533 since I don't have much knowledge about the package, nor parquet or avro.
I'll leave the issue to better hands to send a proper fix.

> AvroParquetWriter instantiated in ParquetIO [1] does not specify the data model.
