stores such as MinIO. MapReduce workloads typically interact with object stores in the same way they do with HDFS. These workloads rely on HDFS atomic rename functionality to complete writing data to the datastore. Object storage operations are atomic by nature and they do not require/implement rename API. The default S3A committer emulates renames through copy and delete APIs. This interaction pattern causes significant loss of performance because of the write amplification. _Netflix_, for example,...

	// Remove the entire folder in case there are leftovers that didn't get cleaned up before restart.
	go removeAll(pathJoin(diskPath, minioMetaTmpBucket+"-old"))

	go renameAllBucketMetacache(diskPath)
}

// Following error message is added to fix a regression in release

	g := errgroup.WithNErrs(len(disks))

	// Rename file on all underlying storage disks.
