Apache Spark for Machine Learning
By :
Data ingestion is the process of importing and loading data into a system, such as a database, a data warehouse, or a data lake. Data ingestion can be done manually or automatically, using various tools and techniques. Data ingestion is the first step in data analysis and machine learning, as it prepares the data for further processing and usage.
Apache Spark is a powerful, distributed data processing system that can read from a wide variety of data sources. Its ability to integrate with many diverse types of data storage systems is one of the reasons for its popularity in big data processing and analytics. Here are some of the key data sources from which Apache Spark can ingest data.
Let’s explore an example of data ingestion from Hadoop Distributed File System (HDFS). Here is a sample code snippet to read data from HDFS:
from pyspark.sql import SparkSession
spark = SparkSession.builder \
.appName("HDFS Read...
