W tym celu można użyć Apache Spark:
1.load your table from mysql via jdbc
2.save it as a parquet file
Przykład:
from pyspark.sql import SparkSession
spark = SparkSession.builder.getOrCreate()
df = spark.read.jdbc("YOUR_MYSQL_JDBC_CONN_STRING", "YOUR_TABLE",properties={"user": "YOUR_USER", "password": "YOUR_PASSWORD"})
df.write.parquet("YOUR_HDFS_FILE")
