Include only scala library in assembly. in this example, hadoop and hbase are already deployed, so I only need scala, not others.

	import AssemblyKeys._

Node.js: Experimenting http send response after closing server socket(no more accepts) It works as I expected. clients get response after server socket is closed.

	request = require 'request'

	url = 'http://localhost:4000'
	i = 0

	sendRequest = (id) ->
	request.get url, (err, res, body) ->
	return console.log err if err
	console.log "#{id} : #{res.statusCode}"

node-hbase example. library is documented in http://www.adaltas.com/projects/node-hbase/ but I found it later. I personally tried hbase with curl and this node-hbase(with inspecting src)

	util = require 'util'
	hbase = require 'hbase'

	inspect = (obj) -> util.inspect(obj, { colors: true, depth: null })
	debug = (err, res) -> console.log err? && err \|\| inspect(res)

	client = hbase {
	host: '--some-host--'
	port: --some-port-number--
	}

AWS autoscaling server rolling restart script. useful when you changed AMI.

Replacing API servers

API 서버들을 최신 버전으로 업데이트하는 스크립트.

기존 스크립트와의 차이는 다음과 같다.

서버를 모두 새로 띄운다.
기존 스크립트는 서버를 한대씩 멈추고 업데이트한 다음, 다시 실행하는 방식으로 작동하였는데, 2~3대의 서버가 있을 때 한대를 내리게 되면 잠시나마 서비스에 상당한
