Ted Yu updated HBASE-8112:
--------------------------

    Description: 
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 HTable#batch(final List<? extends Row>) and refer to the following method:

void batch(final List<?extends Row> actions, final Object[] results) throws IOException, InterruptedException;
