--------------------------------------
Summary: Change PathMetadata to hold S3AFileStatus instead of
FileStatus.
Key: HADOOP-13736
URL: https://issues.apache.org/jira/browse/HADOOP-13736
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Lei (Eddy) Xu
Assignee: Lei (Eddy) Xu
{{S3AFileStatus}} is implemented differently with {{FileStatus}}, for instance
{{S3AFileStatus#isEmptyDirectory()}} is not implemented in {{FileStatus()}}.
And {{access_time}}, {{block_replication}}, {{owner}}, {{group}} and a few
other fields are not meaningful in {{S3AFileStatus}}.
So in the scope of {{S3guard}}, it should use {{S3AFileStatus}} in instead of
{{FileStatus}} in {{PathMetadaa}} to avoid casting the types back and forth in
S3A.
