我橫貫彈性MapReduce,並保持擊中,出現以下錯誤的亞馬遜的例子運行:亞馬遜彈性MapReduce:輸出目錄
Error launching job , Output path already exists.
這裏是跑,我現在用的是作業的命令:
C:\ruby\elastic-mapreduce-cli>ruby elastic-mapreduce --create --stream \
--mapper s3://elasticmapreduce/samples/wordcount/wordSplitter.py \
--input s3://elasticmapreduce/samples/wordcount/input \
--output [A path to a bucket you own on Amazon S3, such as, s3n://myawsbucket] \
--reducer aggregate
Here is where the example comes from here
我下面的輸出目錄Amazon'd方向。存儲桶名稱是s3n://mp.maptester321mark/
。我已經通過自己的所有建議找問題上this url
這裏是我的credentials.json
信息:
{
"access_id": "1234123412",
"private_key": "1234123412",
"keypair": "markkeypair",
"key-pair-file": "C:/Ruby/elastic-mapreduce-cli/markkeypair",
"log_uri": "s3n://mp-mapreduce/",
"region": "us-west-2"
}
爲什麼啊,爲什麼必須S3迫使我們每次創建新的目錄? – 2014-06-15 05:45:49
