hbase-ruby is a pure ruby client for HBase (http://hadoop.apache.org/hbase). It works with the most recent version of HBase REST interface.

== INSTALLTION

$gem sources -a http://gems.github.com
$gem install sishen-hbase-ruby

For those who wants to use hbase in their rails application, can add this line to the environment.rb:
'sishen-hbase-ruby', :lib => "hbase", :source => "http://gems.github.com"
}}

To build the gem yourself:

$rake gem

== USAGE

First download the recent version of hbase (svn checkout http://svn.apache.org/repos/asf/hadoop/hbase/trunk hbase), compile it with 'ant', then launch HBase server:

$bin/start-hbase.sh

Here is the example:
'hbase'

client = HBase::Client.new("http://localhost:60010/api") # this url is the default.
tables = client.list_tables # list available tables

table = client.create_table('users', 'habbit') # create a table whose column_family is habbit

table = client.show_table('users') # show the meta info of table users

row = client.show_row('users', 'sishen') # show the data of row 'sishen' in table 'users'

row2 = client.create_row('users', 'sishen', Time.now.to_i, {:name => 'habbit:football', :value => 'i like football') # create the row 'sishen' with the data in the table 'users'

client.delete_row('users', 'sishen', nil, 'habbit:football') # delete the row 'sishen' of table 'users' with the optional column 'habbit:football'
}}}
