Understanding Files View
You can access files and folders in a cluster's file system using the Ambari web user interface.
Ambari automatically creates one Files View, pointed to the HDFS file system, during cluster deployment. You can also create a custom view from the Files View instance that points to an Amazon Web Services (AWS) S3 file system bucket.
To create a custom Files View to work with files in S3, provide the bucket URL, and valid AWS credentials in thefield when you create the view instance that accesses an S3 bucket. You must enter the AWS credentials as a single string containing no space characters using the following syntax:
fs.defaultFS=s3a://[BUCKET_URL]/; fs.s3a.access.key=[VALID_ACCESS_KEY_STRING]; fs.s3a.secret.key[VALID_SECRET_KEY_STRING]
