Deprecated Methods

Method and Description
org.apache.hadoop.fs.s3a.S3AUtils.closeAll(Logger, Closeable...)
org.apache.hadoop.fs.s3a.S3AUtils.createAwsConf(Configuration, String) use S3AUtils.createAwsConf(Configuration, String, String)

org.apache.hadoop.fs.s3a.s3guard.S3Guard.makeDirsOrdered(MetadataStore, List<Path>, String, boolean, ITtlTimeProvider) this is no longer called by S3AFilesystem.innerMkDirs. See: HADOOP-15079 (January 2018). It is currently retained because of its discussion in the method on atomicity and in case we need to reinstate it or adapt the current process of directory marker creation. But it is not being tested and so may age with time...consider deleting it in future if it's clear there's no need for it.
