Package org.apache.hadoop.fs.s3a.commit.files Description

Persistent data formats for the committers. All of these formats share a base class of PersistentCommitData; the subclasses record

1. The content of a single pending commit (used by the Magic committer).
2. The list of all the files uploaded by a staging committer.
3. The summary information saved in the _SUCCESS file.

There are no guarantees of stability between versions; these are internal structures. The SuccessData file is the one visible to callers after a job completes; it is an unstable manifest intended for testing only.
