> This was brought up by Amit's inquiry on mailing list, entitled 'Batch returned value and exception handling'
> Here is his sample code:
> {code}
> Object[] res = null;
> try {
>   res = table.batch(batch);
> } catch (RetriesExhaustedWithDetailsException retriesExhaustedWithDetailsException) {
>   retriesExhaustedWithDetailsException.printStackTrace();
> }
> if (res == null) {
>   System.out.println("No results - returned null.");
> }
> {code}
> When RetriesExhaustedWithDetailsException was thrown from batch() call, variable res carried value of null.
> Meaning user wouldn't get partial result along with the exception.
> We should deprecate {code}HTable#batch(final List<? extends Row>){code} and refer to the following method:
> void batch(final List<?extends Row> actions, final Object[] results) throws IOException, InterruptedException;
