請問各位先進,

我在上星期二面試某間資訊業界的老公司並拿到offer,

當初面試結果:

from __future__ import with_statement
from fabric.api import run, env, task, abort, local, hosts, parallel, hide, settings, execute, put, sudo
from fabric.network import needs_host
from string import Template
import os.path

env.user ="root"
env.disable_known_hosts = True

default_key_file = os.path.expanduser('~/.ssh/acme_common.pem')

#else
#define logI(tag, fmt, ...)

自我學習，以目前限有材料規劃的 learning path

這只是工具的用法，別忘了吸收資料科學的知識 yo

hadoop 入門速記

1. 用 Hadoop MapReduce Framework 寫程式出來跑得動，跟你想的結果一樣
2. 參考 popcorny 分享的 word count 專案 https://github.com/popcornylu/hadoop-wordcount
3. Map Reduce 演算法概念
4. 弄懂 Map Reduce 演算法各資料處理階段對應至 Hadoop MapReduce Framework 上的 Job Template (之後最佳化會用到)
