Junping Du updated HADOOP-9384: ------------------------------- Fix Version/s: (was: 2.7.1) > Update S3 native fs implementation to use AWS SDK to support authorization > through roles > ---------------------------------------------------------------------------------------- > > Key: HADOOP-9384 > URL: https://issues.apache.org/jira/browse/HADOOP-9384 > Project: Hadoop Common > Issue Type: Improvement > Components: fs/s3 > Environment: Locally: RHEL 6, AWS S3 > Remotely: AWS EC2 (RHEL 6), AWS S3 > Reporter: D. Granit > Priority: Minor > Labels: BB2015-05-TBR > Attachments: HADOOP-9384-v2.patch, HADOOP-9384.patch > > > Currently the S3 native implementation > {{org.apache.hadoop.fs.s3native.Jets3tNativeFileSystemStore}} requires > credentials to be set explicitly. Amazon allows setting credentials for > instances instead of users, via roles. Such are rotated frequently and kept > in a local cache all of which is handled by the AWS SDK in this case the > {{AmazonS3Client}}. The SDK follows a specific order to establish whether > credentials are set explicitly or via a role: > - Environment Variables: AWS_ACCESS_KEY_ID and AWS_SECRET_KEY > - Java System Properties: aws.accessKeyId and aws.secretKey > - Instance Metadata Service, which provides the credentials associated with > the IAM role for the EC2 instance > as seen in > http://docs.aws.amazon.com/IAM/latest/UserGuide/role-usecase-ec2app.html > To support this feature the current {{NativeFileSystemStore}} implementation > needs to be altered to use the AWS SDK instead of the JetS3t S3 libraries. > A request for this feature has previously been raised as part of the Flume > project (FLUME-1691) where the HDFS on top of S3 implementation is used as a > manner of logging into S3 via an HDFS Sink. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
