HBase is ideally suited for real-time environments and this can be best demonstrated by citing the example of our client, a renowned European bank. The results were overwhelming; it reduced the query time from 3 days to 3 minutes. MapReduce was used for data wrangling and to prepare data for subsequent analytics.
Hive was used for custom analytics on top of data processed by MapReduce. The results were impressive; as there was a drastic reduction in the time taken to generate custom analytics — 3 days to 3 hours. Reposted with permission. ZooKeeper: In Hbase, Zookeeper is a centralized monitoring server that maintains configuration information and provides distributed synchronization.
Distributed synchronization is to access the distributed applications running across the cluster with the responsibility of providing coordination services between nodes. In-Depth Model Hbase is one of NoSql column-oriented distributed databases available in apache foundation. HBase gives more performance for retrieving fewer records rather than Hadoop or Hive.
We can perform online real-time analytics using Hbase integrated with the Hadoop ecosystem. Here we have covered HDFS vs HBase head to head comparisons, key differences along with infographics and comparison table. You may also look at the following articles to learn more —.

Hdfs is a storage system and HBase is a relational database. Is it a non-relational database?
While HBase stores data in a column oriented manner where each column is stored together so that, reading becomes faster leveraging real time processing. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Some of the salient features of both the systems are : Hadoop Optimized for streaming access of large files. Follows write-once read-many ideology. Provides low latency access to small amounts of data from within a large data set. Provides flexible data model.
Improve this answer. Tariq Tariq MehdiTAZI definitely. I wouldn't say HBase is ops team's nightmare, but it does have a few areas where there's still some scope of improvement, and the community is working really hard to get that fixed. But that's true for any software. If it fits into your requirements then you should definitely give it a try. Apache Hadoop project includes four key modules Hadoop Common : The common utilities that support the other Hadoop modules. If you need key based access to data when storing or retrieving.
