Before creating E-MapReduce, you need to complete the following prerequisites:

  1. Apply for an Alibaba Cloud account.

    Before applying for the E-MapReduce cluster, you need to have an Alibaba Cloud account to identify yourself through the entire Alibaba Cloud ecosystem. This account can be used not only for E-MapReduce clusters, but also to activate Alibaba Cloud services, such as Object Storage Service (OSS), ApsaraDB for RDS (RDS).

    If you do not have any Alibaba Cloud account, apply for it by referring to Register Cloud Account.

  2. Create an AccessKey (optional)

    You must create at least one AccessKey according to the following steps:

    1. Log on to the official Alibaba Cloud website.
    2. Log on to the Alibaba Cloud console.
    3. Click AccessKeys.
      Notice If a security prompt dialog box appears, click Continue to manage AccessKey .

    4. Click Create AccessKey.
    5. AccessKey is created successfully.
  3. Activate Alibaba Cloud OSS.

    E-MapReduce will store your job logs and run logs in the Alibaba Cloud OSS storage space, so you need to Sign up for OSS. And create a bucket in the same area where you expect to create the cluster, see Create a bucket.

  4. Enable high-end models (optional)

    If you want to use models with 8 cores or more in clusters charged by the Pay-As-You-Go billing method, apply for opening it in ECS first. Apply for high-end models.
