Description: declaration: package: org.apache.hadoop.mapreduce.lib.output.committer.manifest.files

# Package org.apache.hadoop.mapreduce.lib.output.committer.manifest.files

@Public @Unstable package org.apache.hadoop.mapreduce.lib.output.committer.manifest.files
Persistence formats. These are the persistence formats used for passing data from tasks to the job committer `TaskManifest`, and for a `_SUCCESS` file, which is in `ManifestSuccessData`. The `_SUCCESS` file is a copy of the S3A Committer `org.apache.hadoop.fs.s3a.commit.files.ManifestSuccessData`, the intent being that at the JSON-level they are compatible. This is to aid testing/validation and support calls, with one single format to load. Consult the individual formats for their declarations of access; the _SUCCESS file is one which tests may use.
