목 차 what is big data what is map reduce
introducing disco build your own cluster
@ Volume(규모) @ Variety(다양성) @ Velocity(속도) @ Value(가치) what is
big data?
@ 10년전 떡밥 : web 2.0 @ “기술적” 관점에서의 빅
데이터 - map reduce @ 데이터 기반 의사결정을 할 수 있게 해주는 보조도구 - microsoft excel? 마케팅 용어인가요?
bigdata glossary (python 으로 5분 만에 만듬)
what is map reduce
수직 vs 수평
wordcount is hello world of Map Reduce
MapReduce 구현 @ hadoop - 하둡 스트리밍을 이용, 여러 언어에서
사용할 수 있음 - 사실상의 표준 - 수 많은 오픈소스 프로젝트, 보조도구들 - 하지만 자바
왜 하둡/자바 디스하나요?
introducing disco
disco @ erlang + python @ 웹UI와 잡 관리는 erlang
@ 나머지는 전부 python @ 하둡보다 매우 짧은 소스코드(10배?) @ 설치가… 매우 쉬움 @ worker protocol @ 노키아에서 ville tuulos 가 시작
client master slave worker
None
DDFS @ tag based file system

build your own cluster
내 노트북이 리눅스다. @ 공식 싸이트에서 Setting up Disco 따라하면
5분
내 노트북이 맥북이다. @ 공식 싸이트에서 Setting up Disco 따라하면
5분 @ erlang crash dump 생기면 1주일 @ 그냥 vagrant 까세요 @ slave 노드에 pycurl 필요함 @ hostname 안 맞추면 아무것도 안됨
Amazon EC2 @ starcluster : python !!
docker 시도: 실패 (성공하신 분 개인적으로 연락주시 면 후사하겠습니다)
홈 클러스터
None
생각 @ erlang 은 또 하나의 진입장벽이다 @ 왠만한 데이터는
DBMS가 답임 @ HBase Pig Hive 등을 만들어서 쓴다면? @ MR을 더욱 효과적으로? -> 리액 node에 slave-worker 를 띄울 수 있다면 @ MR은 전체 빅데이터 의사결정의 일부분 으로 설계해야 @ 맥 프로 정말 좋음
Where to Start? @ discoproject.org(massive data, minimal code) @ run
tests(disco/tests) -> run_tests_python25 @ follow for -> scipy conference -> ville tuulos(founder of disco) @ NoSQL distilled(MR 설명, 인사이트에 서 번역 나와있음ㅎ)
감사합니다!!
