在AWS上将微型实例用于Elastic MapReduce（EMR）

[英]Using micro instance for Elastic MapReduce(EMR) on AWS

原文 2013-10-14 17:34:26 1 1 amazon-web-services/ amazon-ec2

As amazon charges for an hour even when I use it for minutes. 即使当我使用几分钟，亚马逊也会收取一个小时的费用。 It is getting little expensive to do my school projects or play around with EMR. 开展我的学校项目或玩EMR几乎不贵。 As there are micro instances free I want to make use of these to run my mapreduce jobs, there seem to be no option doing so any help in this regard would be great. 由于我有免费的微型实例，我想利用这些实例来运行我的mapreduce作业，因此似乎没有选择的余地，因此这方面的任何帮助都将是很大的。

Also if that is totally not posibble I wanna know how do I pick any running instance (probably small instance which EMR gives an option to select via console) for mapreduce job? 另外，如果那完全不是摆布，我想知道我该如何选择任何正在运行的实例（可能是小型实例，EMR可以通过控制台选择该实例）进行mapreduce作业？ I am basically planning to run few small instances and get all my small mapreduce jobs use these instances this way I can make most of the money I pay. 我基本上计划运行几个小型实例，并通过这种方式让我所有的小型mapreduce作业都使用这些实例，这样我就可以赚到大部分的钱。

Thanks in advance :) 提前致谢：）

I myself fired-up some EC2 instances and tried to run a map reduce job using Elastic MapReduce console and I was not given any options to use the instances already up. 我本人启动了一些EC2实例，并尝试使用Elastic MapReduce控制台运行map reduce作业，但我没有任何选择可以使用已启动的实例。 Amazon charging on per hour basis is turning out to be bad thing to me at-least. 亚马逊每小时收费对我来说至少是一件坏事。

Please add more info if I am missing or wrong in any way. 如果我有任何缺失或错误，请添加更多信息。

PS: I chose to answer my own question as I did not see any help coming and thought this might someday be helpful to someone experimenting with AWS. PS：我选择回答自己的问题，因为我没有看到任何帮助，并认为这有一天可能对尝试AWS的人有所帮助。
