Parquet-cli convert-csv : Missing option -o for output file path in examples

Examples fail to launch with the current parameters as output file name is not preceded by -o option

{{ "# Create a Parquet file from a CSV file",
"sample.csv -o sample.parquet --schema schema.avsc",
"# Create a Parquet file in HDFS from local CSV",
"path/to/sample.csv -o hdfs:/user/me/sample.parquet --schema schema.avsc",
"# Create an Avro file from CSV data in S3",
"s3:/data/path/sample.csv -o sample.avro --format avro --schema s3:/schemas/schema.avsc"}}

I have checked the first example with the -o, it works.
I have not checked the second and third examples.

Best regards,

Christophe

Review the parquet-cli documentation containing the CSV conversion examples in this issue. Confirm the first example and check the HDFS and S3 examples, then update the examples so each output path uses the -o option and all commands launch successfully.
