안녕하세요. RHadoop에 막 입문한 학생입니다.

1. 하둡2.0을 가상서버로 Cluster 설정을 한 상태입니다.(Master : namenode, nodemanager, resourcemanager, secondarynamenode, datanode)(Slave : nodemanager, datanode) 이 위에다 rhdfs, rmr, rhbase를 설치하는게 맞나요? 그리고 rstudio는 필수적으로 활용되고 있나요?

2.R언어 그대로 활용해서 MapReduce를 할 수 있는 게 맞나요? GitHub, r-project외에 참고할만한 RHdoop관련 사이트나 문서 주소 알려주시면 감사합니다.

3.간단한 테스팅으로 OpenAPI를 이용해서 그 결과값을 RHadoop으로 나타내려고 하는데 주의해야할 점은 무엇이 있을까요? 답변해주시면 감사합니다.

Hi.. I'm student starting RHadoop. I have a questions.

1. I was set up l Hadoop2.0 on CentOS(Multi-node Cluster). on this status, install rhdfs /  rmr / rhbase right? and Rstudio is necessary generally?

2. R language is equivalent to R language on Hadoop?????? please let me know useful site/URL/pdf except GitHub and r-project.

3. I plan on testing. using the OpenAPI(input). please let me know cautions. Thank you

This question has no answer unless you provide versions of everything. Besides that, we can test only a few combinations so you have two options: install whatever combination we tested (Hadoop, OS and RHadoop packages) or try your own and run the tests yourselves to make sure the combination is compatible. Asking about a random combination of Hadoop, OS and rhadoop packages will get you the "we don't know" answer with high probability. Testing means running R CMD check. For rmr2, you need to install an additional package, quickcheck. That's it. 
 
and Rstudio is necessary generally?

No
 

2. R language is equivalent to R language on Hadoop?????? please let me know useful site/URL/pdf except GitHub and r-project.

Please define R language on Hadoop and equivalence of languages. Sorry, we put everything on github, documentation, code, you name it. I think the (paid) enterprise version comes with a pdf manual for people who still use printers in the enterprise, but I doubt the value of the enterprise version is in the pdf manual.
 

3. I plan on testing. using the OpenAPI(input). please let me know cautions. Thank you

I am not familiar with this. Regards


Antonio
