Is Spark and Hadoop the same?
Apache Hadoop and Apache Spark are both open-source frameworks for big data processing with some key differences. Hadoop uses the MapReduce to process data, while Spark uses resilient distributed datasets (RDDs).
What is Spark in Hadoop?
Spark is a fast and general processing engine compatible with Hadoop data. It can run in Hadoop clusters through YARN or Spark’s standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat.
What is Apache spark simple explanation?
Apache Spark is a powerful open-source processing engine built around speed, ease of use, and sophisticated analytics, with APIs in Java, Scala, Python, R, and SQL. Spark runs programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.
What is Hadoop in simple terms?
Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.
What is Spark explain the features of Spark?
The main feature of Spark is its in-memory cluster computing that increases the processing speed of an application. Spark is designed to cover a wide range of workloads such as batch applications, iterative algorithms, interactive queries and streaming.
What is Spark streaming?
Spark Streaming is an extension of the core Spark API that allows data engineers and data scientists to process real-time data from various sources including (but not limited to) Kafka, Flume, and Amazon Kinesis. This processed data can be pushed out to file systems, databases, and live dashboards.
What is Apache spark exactly and what are its pros and cons?
Pros and Cons of Apache Spark
| Apache Spark | Advantages | Disadvantages |
|---|---|---|
| Advanced Analytics | Fewer Algorithms | |
| Dynamic in Nature | Small Files Issue | |
| Multilingual | Window Criteria | |
| Apache Spark is powerful | Doesn’t suit for a multi-user environment |
What is difference between Hadoop and big data?
Definition: Hadoop is a kind of framework that can handle the huge volume of Big Data and process it, whereas Big Data is just a large volume of the Data which can be in unstructured and structured data.
What is Hadoop and how it works?
Hadoop is an Apache open source framework written in java that allows distributed processing of large datasets across clusters of computers using simple programming models. The Hadoop framework application works in an environment that provides distributed storage and computation across clusters of computers.
