>                 Key: HBASE-7806
>                 URL: https://issues.apache.org/jira/browse/HBASE-7806
>             Project: HBase
>          Issue Type: Task
>          Components: Filesystem Integration, regionserver
>    Affects Versions: 0.95.2
>            Reporter: Matteo Bertozzi
>            Priority: Minor
>         Attachments: HBASE-7806.pdf

> Motivations:
> * No way to change the fs layout without touching all the code (and breaking stuff)
> * Each test create is own mocked fs layout: mkdir(region), mkdir(new Path(region, family))
> * new Path(table, region, family, hfile) is everywhere
> * DIR_NAME constants are not in a single place
> * lots of code does a the same for (region.listStatus()) for (family.listStatus()) ...
> Goals:
>  * Central point for all the fs operations
>  ** Make easier the file creation
>  ** Make easier the store files retrival (with proper reference, link handling)
>  * Removing all the new Path() from the code
>  * Removing all the fs.listStatus() from the code
>  * Cleanup the tests to use the new classes of creating mocks object
>  * Reduce the code (in theory there should be less line than before once this refactor is complete)
> Since the fs operations are all over the code, the refactor must be gradual, and step by step limiting the internal fs layout visibility.
