> exists() calls logs FileNotFoundException in namenode log

> exists() was modified to invoke getFileStatus() internally. But
> getFileStatus() throws FileNotFoundException for files which does not exists
> and this is logged in RPC$Server for each exists() call. One way to get rid
> of these messages is at the Name Node, catch FileNotFoundException and return
> null. In this case, RPC would not log it in namenode log. But at the client
> end we might have to check for null on all calls of getFileStatus(). Other
> option at client end is to construct FileNotFoundException() when
> getFileInfo() returns null.
