Installation
Bundler
Add to Gemfile and run bundle install:
gem 'hbase2-rb'Without Bundler
Install the gem:
gem install hbase2-rbRequire it explicitly in your scripts:
require "rubygems"
require "hbase2-rb"Versioning
The base version of the gem matches the version of HBase the interface was generated against.
For instance, when using HBase 1.2.0:
gem 'hbase-rb', '~> 1.2.0'Usage
For example:
socket = Thrift::Socket.new('localhost', 9090)
transport = Thrift::BufferedTransport.new(socket)
transport.open
protocol = Thrift::BinaryProtocol.new(transport)
client = HBase2::Client.new(protocol)Writing Rows
# Assuming a table "mytable" and a column family "c"
column_value = HBase2::TColumnValue.new
column_value.family = 'c'
column_value.qualifier = 'foo'
column_value.value = 'bar'
put = HBase2::TPut.new row: 'abc123', columnValues: [column_value]
client.put('mytable', put)Reading Rows
# Assuming a table "mytable" and a column family "c"
get = HBase2::TGet.new row: 'abc123'
result = client.get('mytable', get)
if result.row
result.columnValues.each do |column|
puts "#{column.family}:#{column.qualifier} #{column.value}"
end
end
