HBase has a close relationship with Java. In the Java world, REST is a way to interact with objects over the Web. HBase provides the REST service that runs as a separate process and communicates with HBase. This REST service uses the same client API to access HBase.
For a REST-based client to make a connection to an HBase cluster, first start the REST server on the HBase Master as follows:
[root@localhost bin]# hbase rest ... usage: bin/hbase rest start [--infoport <arg>] [-p <arg>] [-ro] --infoport <arg> Port for web UI -p,--port <arg> Port to bind to [default: 8080] -ro,--readonly Respond only to GET HTTP method requests [default: false]
To run the REST server as a daemon, execute the following command:
bin/hbase-daemon.sh start|stop rest [--infoport <port>] [-p <port>] [-ro]
For example, launch the REST service, listening on port 9999 using the following command:
