Cross-account Access to AWS Glue

To connect your e6data Workspace to an AWS Glue Metastore and S3 data source in a different cloud account, please follow the four (4) steps below:

This guide assumes:

  • the e6data Workspace (clusters/compute) is installed in a cloud account named Account A.

  • the AWS Glue metastore & S3 data stores are located in a different cloud account named Account B.

  • Both Account A & Account B are in the same AWS region.

Step 1: Create policies to access Glue & S3 data sources in Account B

  1. Sign in to the Account B AWS Console.

  2. Search for IAM.

  3. Click Policies

  4. Choose Create policy.

  5. In the Policy editor section, choose the JSON option.

  6. Edit the policy provided below:

    1. Replace <DATASTORE_BUCKET_ARN> with the ARN of the S3 bucket/s containing the data

    2. Replace <GLUE_REGION> with the region that the Glue metastore is located in.

    3. Replace <ACCOUNT_B_ID> with the Account ID of the account containing the S3 bucket & Glue metastore.
