Ted Yu commented on HBASE-8112:
-------------------------------
Pardon me for introducing the smiley in the first place.
Here is the complete method signature:
{code}
public Object[] batch(final List<? extends Row> actions)
throws InterruptedException, IOException {
{code}
Users may rely on the IOE from this method (just guessing).
Basically we cannot return partial results and keep throwing the IOException at
the same time.
Jean-Marc mentioned, on the mailing list, that the method from HTableInterface
should be deprecated (same as my intention).
> Deprecate HTable#batch(final List<? extends Row>)

> Key: HBASE-8112
> URL: https://issues.apache.org/jira/browse/HBASE-8112
> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
> Priority: Minor
>
> 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;
