Subject [jira] [Commented] (HADOOP-12910) Add new FileSystem API to support asynchronous method calls
Date Thu, 10 Mar 2016 16:25:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12910?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15189492#comment-15189492
] 

Allen Wittenauer commented on HADOOP-12910:
-------------------------------------------

Classes, errors, etc should be 'whats' not 'whens'.  AsyncFileSystem is waaaaaaaaay better.
(Yes, I think Java's Future object is a terrible name.)

Also, calling this a FileSystem sort of underscores that FileContext might as well get tossed
since not even Hadoop people bother to use it, despite being a better defined API.

> Add a new API, namely FutureFileSystem (or AsynchronousFileSystem, if it is a better
name).  All the APIs in FutureFileSystem are the same as FileSystem except that the return
type is wrapped by Future, e.g.
> {code}
>   //FileSystem
>   public boolean rename(Path src, Path dst) throws IOException;
>   //FutureFileSystem
>   public Future<Boolean> rename(Path src, Path dst) throws IOException;
> {code}
> Note that FutureFileSystem does not extend FileSystem.
