> when using function waitForCompletion in a try block, exceptions are not handled :
> waitForCompletion might throw  : IOException, InterruptedException, ClassNotFoundException
> so when calling this function in a try block, we should use a catch block to handle potential Exceptions.
> public Map<String, Object> run(Map<String, Object> args) throws Exception {
> ...
> try {
>       currentJob.waitForCompletion(true);
>     } finally {
>       ToolUtil.recordJobStatus(null, currentJob, results);
>       if (!currentJob.isSuccessful()) {
>         fileSystem.delete(tmpFolder, true);
>         return results;
>       }
>     }
> ...
> }
