Subject [jira] [Commented] (HADOOP-13651) S3Guard: S3AFileSystem Integration with MetadataStore
Date Thu, 17 Nov 2016 10:17:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15673327#comment-15673327

Steve Loughran commented on HADOOP-13651:

the MiniYarnCluster is HADOOP-13801; need to spend more time with git blame to idenfity what
changed there. It's doing wordcount, and the format of the response has changed ... not sure
it's in s3a tests, or the output format really has changed from text to hadoop writeable output.

Root dir tests on object stores are always fussy.

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