Subject [jira] [Updated] (HADOOP-12910) Add new FileSystem API to support asynchronous method calls
Date Thu, 10 Mar 2016 00:50:41 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tsz Wo Nicholas Sze updated HADOOP-12910:
-----------------------------------------
    Description: 
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.

  was:

 All the APIs in FutureFileSystem are the same as FileSystem except that the return type is
wrapped by Future and they do not throw IOException, 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.
