About HBase

HBase is part of the Hadoop ecosystem from the Apache Software Foundation. It is a column oriented database (think NoSQL) that really scale and is modelled after Google papers and its BigTable database.

Installing HBase

Downloading the Cloudera CDH or Hortonworks HDP sandboxes are the easiest ways to get started. If you run Ubuntu, Debian or RedHat, those two distributions provide packages integrated with apt-get and yum. It is also possible to download the binaries from the official website.

Starting HBase

Assuming ${HBASE_HOME}/bin is in your classpath, starting HBase with REST connector is as follow:

start-hbase.sh
hbase-daemon.sh start rest

And stopping:

hbase-daemon.sh stop rest
stop-hbase.sh

Or

ps ax | grep hbase | awk '{print $1}' | xargs kill -9

Installing node-hbase

Use NPM or YARN to install the HBase client.

npm install hbase

Creating a new instance

const hbase = require('hbase')
const client = hbase({
  host: '127.0.0.1',
  port: 8080
})

Or

const hbase = require('hbase')
const client = new hbase.Client({
  host: '127.0.0.1',
  port: 8080
})
