How to Get an Elastic MapReduce Developer Account (開発アカウント取得)
This section explains how to sign up for anElastic MapReduce developer account. This procedure automatically registers you to use Amazon S3 and Amazon EC2 unless you have already registered yourself for those products.
To sign up for an Elastic MapReduce developer account
1. Go to http://elasticmapreduce.amazon.com.
2. Click Sign up for this Service.
3. Log in with your AWS account login and password.
4. Click Sign Up and follow the instructions on the subsequent pages.
This procedure also assigns you an AWS account, which is similar to an Amazon.com customer account except that the AWS account gives you access to Amazon web services.
Amazon S3 Bucket Creation (S3バケット作成)
Before you can use the examples in this guide you must create a bucket with write permissions where Elastic MapReduce can upload results. The following tools make creating a bucket, putting data in the bucket, and retrieving data from the bucket easy:
* S3curl
For more information, go to http://developer.amazonwebservices.com/connect/entry.jspa?externalID=128.
* Amazon S3 Firefox Organizer (S3Fox)
For more information. go to https://addons.mozilla.org/en-US/firefox/addon/3247.
* Amazon S3 tool
For more information, go to http://developer.amazonwebservices.com/connect/entry.jspa?externalID=739.
Consult each tool's documentation for more information.
Make a note of your bucket name so that you can use it in the sample requests.
Naming Conventions for Amazon S3 Buckets(S3バケットの名付けルール)
The bucket you create must be DNS friendly. We recommend that you use bucket names that conform with the following DNS requirements:
* Bucket names should not contain underscores (_)(アンダースコア禁止)
* Bucket names should be between 3 and 63 characters long(３文字以上６３文字まで）
* Bucket names should not end with a dash（ダッシュで終わらない)
* Bucket names cannot contain dashes next to periods (e.g. "my-.bucket.com" and "my.-bucket" are invalid)（ピリオドの次にダッシュはだめ）
For more details, go to http://docs.amazonwebservices.com/AmazonS3/latest/index.html?BucketRestrictions.html.
[Tip] Tip
Make a note of your bucket name so that you can use it in this guide.
How to Assign Bucket Permissions（バケットのパーミッション）
After creating a bucket, make sure to set appropriate permissions on it. Typically, you give the owner read and write access and authenticated users read access.
How you give permission depends on the tool. Here we show you using Amazon S3 FireFlox Organizer.
To set permissions on a bucket using S3Fox
1. Open S3Fox and navigate to the bucket you created.
2. Right-click on your bucket, select the permissions you want to give to each user type, and click OK.
You've now created your bucket and assigned it permissions. You will use this bucket in the following tutorial as the place where you will upload your processed data.
