What is HBase and features of HBase?

HBase is a column-oriented non-relational database management system that runs on top of Hadoop Distributed File System (HDFS). HBase provides a fault-tolerant way of storing sparse data sets, which are common in many big data use cases.

What are various features of HBase?

Features of HBase

• HBase is linearly scalable.
• It has automatic failure support.
• It provides consistent read and writes.
• It integrates with Hadoop, both as a source and a destination.
• It has easy java API for client.
• It provides data replication across clusters.

Why we required HBase tool in Hadoop?

HBase is primarily used to store and process unstructured Hadoop data as a lake. You can also use HBase as your warehouse for all Hadoop data, but we primarily see it used for write-heavy operations.

How does HBase work in Hadoop?

HBase is simple, just add new nodes to the cluster, HBase will automatically split horizontally, and seamless integration with Hadoop ensures data reliability (HDFS) and high performance of massive data analysis (MapReduce ).

Does HBase need Hadoop?

HBase can be used without Hadoop. Running HBase in standalone mode will use the local file system. The reason arbitrary databases cannot be run on Hadoop is because HDFS is an append-only file system, and not POSIX compliant. Most SQL databases require the ability to seek and modify existing files.

Why is Hadoop HDFS more reliable than HBase?

HDFS lacks an in-memory processing engine slowing down the process of data analysis; as it is using plain old MapReduce to do it. HBase, on the contrary, boasts of an in-memory processing engine that drastically increases the speed of read/write. HDFS is very transparent in its execution of data analysis.

Is Apache Hive a database?

No, we cannot call Apache Hive a relational database, as it is a data warehouse which is built on top of Apache Hadoop for providing data summarization, query and, analysis. It differs from a relational database in a way that it stores schema in a database and processed data into HDFS.

What are the components of Apache HBase?

HBase architecture has 3 main components: HMaster, Region Server, Zookeeper. The implementation of Master Server in HBase is HMaster. It is a process in which regions are assigned to region server as well as DDL (create, delete table) operations.

What is HBase in Hadoop ecosystem?

HBase. Apache HBase is a Hadoop ecosystem component which is a distributed database that was designed to store structured data in tables that could have billions of row and millions of columns. HBase is scalable, distributed, and NoSQL database that is built on top of HDFS.

Which among the following is the component of Apache HBase *?

HBase architecture has 3 important components- HMaster, Region Server and ZooKeeper.

What are some common uses for Apache Hadoop?

Security and Law Enforcement. The USA’s national security agency uses Hadoop to prevent terrorist attacks,and It is used to detect and prevent cyber-attacks.

What are some of the use cases of Apache HBase?

HBase Use Cases Storing billions of CDR (Call detailed recording) log records generated by telecom domain Providing real-time access to CDR logs and billing information of customers Provide cost-effective solution comparing to traditional database systems

What is the difference between HBase and Hadoop?
