What is the biggest advantage of Hadoop?

Means Hadoop provides us 2 main benefits with the cost one is it’s open-source means free to use and the other is that it uses commodity hardware which is also inexpensive. Hadoop is a highly scalable model. A large amount of data is divided into multiple inexpensive machines in a cluster which is processed parallelly.

What are key advantages in Hadoop?

Hadoop is a highly scalable storage platform because it can store and distribute very large data sets across hundreds of inexpensive servers that operate in parallel. Unlike traditional relational database systems (RDBMS) that can’t scale to process large amounts of data.

What is Cassandra in Hadoop?

Cassandra, like Hadoop, is designed to use low-cost commodity storage to deliver a distributed architecture. That means using the hard drives that are attached to the virtual and physical machines in the data center instead of some kind of storage array. Cassandra data is stored in storage as an SSTable.

What are the core components of Hadoop?

Key Hadoop Components. The three major categories of components in a Hadoop deployment are Client machines, Masters nodes, and Slave nodes. The Master nodes oversees the two key functional pieces that make up Hadoop: storing lots of data (HDFS), and running parallel computations on all that data (Map Reduce).
