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.

> consistency and caching.
> Implementation should have minimal overhead when no MetadataStore is
