using API to determine when async file copy is complete

Is there a way to determine how many complete replicas there are of a file?  That is, can I find out that the async replication has completed?  And how many replicas are complete?  I'd like to do this via the Java API.



Thanks,

Martin

Hi Martin,

Have a look at the waitForReplication() function in  FsShell.java in
hadoop-common. It does what you're looking for.
