S3ClientBuilder

trait S3ClientBuilder extends Serializable

Interface to build an S3 client. The object io.treeverse.clients.conditional.S3ClientBuilder -- conditionally defined in a separate file according to the supported Hadoop version -- implements this trait. (Scala requires companion objects to be defined in the same file, so it cannot be a companion.)

Abstract Value Members

  1. abstract def build(hc: Configuration, bucket: String, region: String, numRetries: Int): AmazonS3

    Return a configured Amazon S3 client similar to the one S3A would use.

    Return a configured Amazon S3 client similar to the one S3A would use. On Hadoop versions >=3, S3A can assume a role, and the returned S3 client will similarly assume that role.

    hc

    (partial) Hadoop configuration of fs.s3a.

    bucket

    that this client will access.

    region

    to find this bucket.

    numRetries

    number of times to retry on AWS.

    Name of property from which S3A fetches whether to use path-style S3 access or host-style.

    org.apache.hadoop.fs.s3a.Constants defines this property only starting with version 2.8. Define it here to support earlier versions.
