In my previous post, I demonstrated how to write and read parquet files in Spark/Scala. The parquet file destination is a local folder. Write and Read Parquet Files in Spark/Scala. In this page, I am going to demonstrate how to write and read parquet files in HDFS. Sample code import bltadwin.ru{SparkConf, SparkContext}. As an example, I took a 2 MB CSV file and converted it to a parquet file which was almost 40% smaller in file size. Parquet storage format typically provides significant savings in file sizes. As more and more organizations are moving to the cloud, reducing file sizes can provide an immediate benefit in savings on storage costs. I am looking to read a parquet file that is stored in HDFS and I am using Python to do this. I have this code below but it does not open the files in HDFS. Can you help me change the code to do th.
