/**
 * Persistent data formats for the committers.
 *
 * All of these formats share a base class of
 * {@link org.apache.hadoop.fs.s3a.commit.files.PersistentCommitData};
 * the subclasses record
 * <ol>
 *   <li>The content of a single pending commit
 *   (used by the Magic committer).</li>
 *   <li>The list of all the files uploaded by a staging committer.</li>
 *   <li>The summary information saved in the {@code _SUCCESS} file.</li>
 * </ol>
 *
 *
 * The {@link org.apache.hadoop.fs.s3a.commit.files.SuccessData} file is
 * the one visible to callers after a job completes; it is compatible with
 * the manifest committer format persisted in
 * {@code org.apache.hadoop.mapreduce.lib.output.committer.manifest.files.ManifestSuccessData}
