             Summary: S3Guard: instrument MetadataStore for asserting & testing MetadataStoreTestBase
                 Key: HADOOP-14756
                 URL: https://issues.apache.org/jira/browse/HADOOP-14756
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: HADOOP-13345
            Reporter: Steve Loughran
             Fix For: HADOOP-13345


{{MetadataStoreTestBase.testListChildren}} would be improved with the ability to query the features offered by the store, and the outcome of {{put()}}, so probe the correctness of the authoritative mode

# Add predicate to MetadataStore interface  {{supportsAuthoritativeDirectories()}} or similar
# If #1 is true, assert that directory is fully cached after changes
# Add "isNew" flag to MetadataStore.put(DirListingMetadata); use to verify when changes are made
