Aaron Fabbri commented on HADOOP-13448:
---------------------------------------

(Posting here since it is related, but I'd probably add the change as part of 
HADOOP-13452 or a subsequent patch.)

[~cnauroth] how do you feel about adding a FileSystem parameter to 
MetadataStore#initialize()?  The motivation is that I'm adding path 
qualification / normalization to the LocalMetadataStore, and finding I could 
use the associated FileSystem's working directory to make sure it is an 
absolute path.

I'm still trying not to add S3A dependencies unless strictly needed 
(envisioning the directory entry caching features potentially useful to other 
clients).
