Gang Wu / @wgtmac:
Thanks for reporting the issue! I can reproduce it on my end. Let me investigate it.

[asfimport]

Jiashen Zhang / @zhangjiashen:

This error is expected because some names using '-' in schema are invalid, it is thrown from validateName in https://github.com/apache/avro/blob/branch-1.11/lang/java/avro/src/main/java/org/apache/avro/Schema.java, please double check?

[asfimport]

Gang Wu / @wgtmac:
Can we get rid of the schema conversion via AvroSchemaConverter? This file is created by the C++ parquet writer from Apache Arrow. So it does not have to do the conversion.

[asfimport]

Jiashen Zhang / @zhangjiashen:
This Cat supports multiple file formats - Parquet, Avro, Text, it internally needs to converts MessageType to Avro Schema if it is a parquet format, which doesn't support '-' . What do you think we add a new command to cat parquet file format without converting to Avro Schema and we can directly print content given a parquet file? Below is some code sample:

 String input = <parquet file>;

 ParquetReader<SimpleRecord> reader = null;
 try {
 PrintWriter writer = new PrintWriter(Main.out, true);
 reader = ParquetReader.builder(new SimpleReadSupport(), new Path(input)).build();
 ParquetMetadata metadata = ParquetFileReader.readFooter(new Configuration(), new Path(input));
 JsonRecordFormatter.JsonGroupFormatter formatter = JsonRecordFormatter.fromSchema(metadata.getFileMetaData().getSchema());

 for (SimpleRecord value = reader.read(); value != null; value = reader.read()) {
 value.prettyPrint(writer);
 writer.println();
 }
 } finally {
 if (reader != null) {
 try {
 reader.close();
 } catch (Exception ex) {
 }
 }
 }
}

Gang Wu / @wgtmac:
Sorry for the late reply. I'm not sure if it is a good idea to add a new command. Since both head and cat commands have the same issue, can we try/catch the exception and use the JsonRecordFormatter you proposed as a fallback solution if the avro schema conversion fails?
