Apache HBase is the Hadoop database, a distributed, scalable, big data store.
Use Apache HBase™ when you need random, realtime read/write access to your Big Data. This project's goal is the hosting of very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. Apache HBase is an open-source, distributed, versioned, non-relational database modeled after Google's Bigtable: A Distributed Storage System for Structured Data by Chang et al. Just as Bigtable leverages the distributed data storage provided by the Google File System, Apache HBase provides Bigtable-like capabilities on top of Hadoop and HDFS.

Getting Started
http://hbase.apache.org/book.html#quickstart
Set the configuration file hbase-site.xml
More about HBase configuration file.
Set the JAVA_HOME
On MacOS X
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
Installation
Download the latest version of the binary :
export $HBASE_VERSION=1.1.0.1 tar xf hbase-$HBASE_VERSION.tgz mv hbase-$VERSION hbase cd hbase
Launch the standalone
bin/start-hbase.sh
Launch the CLI
bin/hbase shell
help create 'sensordata', {NAME => 'sensoreui', VERSIONS => 1, TTL => 2592000, BLOCKCACHE => true}, {NAME => 'timestamp'}, {NAME => 'value'}, {NAME => 'unit'}, {NAME => 'error'} list scan 'sensordata' put 'sensordata', 'sensoreui', 'colfam:qual’, ‘value’ get 'sensordata', 'sensoreui' disable 'sensordata' drop 'sensordata'
Launch the Node.js client
Voir le package https://www.npmjs.com/package/hbase-client
npm install hbase-client --save
Stop the standalone server
bin/stop-hbase.sh
