Real-Time Hadoop Processing Components, Frameworks, and Benefits
What is Real-Time Hadoop Processing?
Real-time Hadoop processing refers to the capability of processing data in real time as it is generated, instead of waiting for it to accumulate in batches. This is achieved by utilizing streaming frameworks like Apache Spark Streaming or Apache Storm to process data concurrently with its ingestion into the Hadoop ecosystem.

Differences between Real-Time Processing and Batch Processing in Hadoop
Real-time processing in Hadoop differs from batch processing, which is the conventional approach. Batch processing involves loading data into Hadoop and processing it in larger batches using techniques like MapReduce. While batch processing is suitable for handling extensive datasets, it may not be efficient for analyzing data requiring real-time insights.
Real-time processing, on the other hand, enables immediate analysis by leveraging streaming frameworks. These frameworks process data continuously without waiting for it to accumulate in batches, ensuring timely analysis.
