[jira] [Created] (HADOOP-12807) S3AFileSystem should read AWS credentials from environment variables

Tobin Baker created HADOOP-12807:
------------------------------------

             Summary: S3AFileSystem should read AWS credentials from environment variables
                 Key: HADOOP-12807
                 URL: https://issues.apache.org/jira/browse/HADOOP-12807
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
            Reporter: Tobin Baker
            Priority: Minor
             Fix For: 2.7.3


Unlike the {{DefaultAWSCredentialsProviderChain}} in the AWS SDK, the {{AWSCredentialsProviderChain}} constructed by {{S3AFileSystem}} does not include an {{EnvironmentVariableCredentialsProvider}} instance. This prevents users from supplying AWS credentials in the environment variables {{AWS_ACCESS_KEY_ID}} and {{AWS_SECRET_ACCESS_KEY}}, which is the only alternative in some scenarios.

In my scenario, I need to access S3 from within a test running in a CI environment that does not support IAM roles but does allow me to supply encrypted environment variables. Thus, the only secure approach I can use is to supply my AWS credentials in environment variables (plaintext configuration files are out of the question).
