["Aaron Fabbri (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-13452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron Fabbri updated HADOOP-13452:
----------------------------------
    Attachment: HADOOP-13452.001.patch

Attaching v1 patch for LocalMetadataStore and unit test.  I wanted to get this out for review.  Tests pass and test-patch was clean.  This patch applies on top of HADOOP-13573

Still need to do:

- Filter incoming Paths.. something like S3AFileSystem#pathToKey()
- LruHashMap should have a unit test.

> Implement an S3A access policy based on an in-memory metadata store.  This can provide consistency within the same client without needing to integrate with an external system.
