[jira] [Updated] (HADOOP-12910) Add new FileSystem API to support
asynchronous method calls
[ 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.
