Subject [jira] [Created] (HBASE-8112) Deprecate HTable#batch(final List<? extends Row>)

Ted Yu created HBASE-8112:
-----------------------------

             Summary: 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


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;
