> When loading the snapshot, ZooKeeper will consider only the 'snapshots with
> atleast 10 bytes size'. Otherwsie it will ignore and just return without
> closing the RandomAccessFile.
> {noformat}
> Util.isValidSnapshot() having the following logic.
> // Check for a valid snapshot
> RandomAccessFile raf = new RandomAccessFile(f, "r");
> // including the header and the last / bytes
> // the snapshot should be atleast 10 bytes
> if (raf.length() < 10) {
> return false;
> }
> {noformat}
> Since the snapshot file validation logic is outside try block, it won't go to
> the finally block and will be leaked.
> Suggestion: Move the validation logic to the try/catch block.
