Venki Korukanti created DRILL-824:
-------------------------------------
Summary: MergingRecordBatch.next() fails to reallocate the
outgoing vectors if copyFromSafe returns false
Key: DRILL-824
URL: https://issues.apache.org/jira/browse/DRILL-824
Project: Apache Drill
Issue Type: Bug
Reporter: Venki Korukanti
Assignee: Venki Korukanti
{code}
public IterOutcome next()
while (!pqueue.isEmpty()) {
// pop next value from pq and copy to outgoing batch
Node node = pqueue.peek();
if (!copyRecordToOutgoingBatch(node)) {
break;
}
...
}
...
}
{code}
If the {{copyRecordToOutgoingBatch}} fails, we send the current outgoing batch,
but we don't reallocate outgoing batch when we reenter {{next}} which leads to
DeadBuf exceptions.
