Furthermore, when to use HBase?
Applications of HBase It is used whenever there is a need to write heavy applications. HBase is used whenever we need to provide fast random access to available data. Companies such as Facebook, Twitter, Yahoo, and Adobe use HBase internally.
Accordingly, why do we need zookeeper for HBase? HBase distributed application installation depends on a running ZooKeeper cluster. Apache HBase uses ZooKeeper to track the status of distributed data throughout the master and region servers with the help of centralized configuration management and distributed mutex mechanisms. Here are some of the use-cases of HBase −
