Subject [jira] [Commented] (HADOOP-13651) S3Guard: S3AFileSystem Integration with MetadataStore
Date Fri, 04 Nov 2016 05:10:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15635275#comment-15635275
] 

Aaron Fabbri commented on HADOOP-13651:
---------------------------------------

I will address above pre-commit issues after I get the feature branch rebased on trunk.

[~stevel@apache.org], when feature branches get merged to trunk, is it as a fast-forward,
or as a merge commit?

Many of the commits on this feature branch need reworking for trunk s3a changes, and I'm wondering
if I should go through the history one by one, rewriting those commits to work against trunk
(e.g. S3AFileStatus constructor args changed), or just add a Fixup commit on top of the feature
branch to get it to compile on trunk's S3A code.)

> Modify S3AFileSystem et al. to optionally use a MetadataStore for metadata consistency
and caching.
> Implementation should have minimal overhead when no MetadataStore is configured.
