[目的]======================================================
在ubuntu16上安裝R和hadoop環境
並用rhdfs和rmr2執行簡單範例
[問題]======================================================
(問題1):在library(rmr2)時會出現錯誤訊息:
Please review your hadoop settings. See help(hadoop.settings)
(問題2):library(rhdfs)後
init.hdfs()出現錯誤訊息:
17/01/11 17:20:17 WARN util.NativeCodeLoader:
Unable to load native-hadoop
library for your platform...
using builtin-java classes where applicable
猜或許是hadoop streaming設置錯了??
[安裝過程]====================================================
啟動hadoop
cd ~/hadoop && sbin/start-all.sh
