Handles load balancing of the regions across region servers. We assure that you will not find any problem in this HBase tutorial. That means clients can directly communicate with HBase Region Servers while accessing data. We have to import data present in the file into an HBase table by creating it through Java API. - Online conguration state is maintained in ZooKeeper. The database may be present on the same machine or any remote machine connected via a network. All these HBase components have their own use and requirements which we will see in details later in this HBase architecture explanation guide. The Hadoop Distributed File System (HDFS) is a distributed file system for Hadoop. Regions are vertically divided by column families into Stores.

This code implements the corresponding dynamic behavior of the page. But if there is any mistake, please post the problem in contact form. Database systems can be centralized, or client-server . It contains a master/slave architecture. Therefore it provides programmatic access to Data Manipulation Language (DML). HBase tables are mainly divided into regions and are being served by Region servers. It provides SQL type language for querying called HiveQL or HQL. Region servers can be added or removed as per requirement. Initially Hive was developed by Facebook, later the Apache Software Foundation took it up and developed it further as an open source under the name Apache Hive.
