Nicholas Chammas commented on HADOOP-16930: ------------------------------------------- cc [~ste...@apache.org] - I'd be happy to work on the doc update if I've understood the issue correctly. > Add com.amazonaws.auth.profile.ProfileCredentialsProvider to hadoop-aws docs > ---------------------------------------------------------------------------- > > Key: HADOOP-16930 > URL: https://issues.apache.org/jira/browse/HADOOP-16930 > Project: Hadoop Common > Issue Type: Improvement > Components: documentation, fs/s3 > Reporter: Nicholas Chammas > Priority: Minor > > There is a very, very useful S3A authentication method that is not currently > documented: {{com.amazonaws.auth.profile.ProfileCredentialsProvider}} > This provider lets you source your AWS credentials from a shared credentials > file, typically stored under {{~/.aws/credentials}}, using a [named > profile|https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html]. > All you need is to set the {{AWS_PROFILE}} environment variable, and the > provider will get the appropriate credentials for you. > I discovered this from my coworkers, but cannot find it in the docs for > hadoop-aws. I'd expect to see it at least mentioned in [this > section|https://hadoop.apache.org/docs/r2.9.2/hadoop-aws/tools/hadoop-aws/index.html#S3A_Authentication_methods]. > It should probably be added to the docs for every minor release that > supports it, which I'd guess includes 2.8 on up. > (This provider should probably also be added to the default list of > credential provider classes, but we can address that in another ticket. I can > say that at least in 2.9.2, it's not in the default list.) > (This is not to be confused with > {{com.amazonaws.auth.InstanceProfileCredentialsProvider}}, which serves a > completely different purpose.) -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
