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

检查本 issue 中包含 CSV 转换示例的 parquet-cli 文档。确认第一个示例并检查 HDFS 和 S3 示例，然后更新这些示例，使每个输出路径都使用 -o 选项，并确保所有命令都能成功启动。
