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

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--
}

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}"

Include only scala library in assembly. in this example, hadoop and hbase are already deployed, so I only need scala, not others.
import AssemblyKeys._
assemblySettings
name := "HelloWorld"
version := "0.0.1"
scalaVersion := "2.9.2"
