[GitHub] [beam] stiv1qaz1 opened a new issue, #26318: [Bug]: SchemaParseException: Can't redefine: list

stiv1qaz1 opened a new issue, #26318:
URL: https://github.com/apache/beam/issues/26318

   ### What happened?
   
   
   
   When BigQueryIO tries to convert a structure to an Avro schema, it generates a schema for the structure. However, when BigQueryIO tries to convert the schema to a string, it crashes with an error.
   
   It cannot convert schemas that reuse group field names in inner structures. This is because Avro record types must have unique names, and the converter creates an Avro record schema in this case. The result is an invalid Avro schema. 
   
   The `org.apache.avro.Schema$Names` map is a map that stores the names of the fields in an Avro schema. When the code tries to register the identifier org.apache.beam.sdk.io.gcp.bigquery.identifier twice in the map, it causes a collision resulting in the following stack trace downstream:
   
   ```
