Subject [jira] Commented: (HADOOP-6223) New improved FileSystem interface for those implementing new files systems.
Date Tue, 15 Sep 2009 22:17:57 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755739#action_12755739
] 

Jakob Homan commented on HADOOP-6223:
-------------------------------------

Rather than AbstractFileSystem.java, just Fs.java may be better since it (1) follows typical
naming convention for an abstract class and its implementing classes, (2) doesn't conflict
with Andrew File System and (3) an interface should be indistinguishable from the implementation,
particularly in name.

> The FileContext API (HADOOP-4952) provides an improved interface for the application
writer.
> This lets us simplify the FileSystem API since it will no longer need to deal with notions
of default filesystem [ / ],  wd, and config
> defaults for blocksize, replication factor etc. Further it will not need the many overloaded
methods for create() and open() since
> the FileContext API provides that convenience.
> The FileSystem API can be simplified and can now be restricted to those implementing
new file systems.
> This jira proposes that we create new file system API,  and deprecate FileSystem API
after a few releases.
