> DFSClient should diff the writing files with namespaceId and iNodeId, because the writing files may belongs to different namespace with the same iNodeId.
> And the related code as bellows:
> {code:java}
> public void putFileBeingWritten(final long inodeId,
>       final DFSOutputStream out) {
>     synchronized(filesBeingWritten) {
>       filesBeingWritten.put(inodeId, out);
>       // update the last lease renewal time only when there was no
>       // writes. once there is one write stream open, the lease renewer
>       // thread keeps it updated well with in anyone's expiration time.
>       if (lastLeaseRenewal == 0) {
>         updateLastLeaseRenewal();
>       }
>     }
>   }
> {code}
