我横贯弹性MapReduce,并保持击中,出现以下错误的亚马逊的例子运行:亚马逊弹性MapReduce:输出目录
Error launching job , Output path already exists.
这里是跑,我现在用的是作业的命令:
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
我下面的输出目录Amazon'd方向。存储桶名称是s3n://mp.maptester321mark/
。我已经通过自己的所有建议找问题上this url
这里是我的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"
}
为什么啊,为什么必须S3迫使我们每次创建新的目录? – 2014-06-15 05:45:49
