---------------------------------------
Summary: AllocationHelper.allocateNew() doesn't have a consistent
behavior when it can't allocate
Key: DRILL-2947
URL: https://issues.apache.org/jira/browse/DRILL-2947
Project: Apache Drill
Issue Type: Sub-task
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
AllocationHelper.allocateNew(...) has the following implementation:
{code}
public static boolean allocateNew(ValueVector v, int valueCount){
if (v instanceof FixedWidthVector) {
((FixedWidthVector) v).allocateNew(valueCount);
return true;
} else {
return v.allocateNewSafe();
}
}
{code}
If it can't allocate the memory it will either return false or throw an
_OutOfMemoryRuntimeException_ depending on the class of v.
Some operators that use this method, like _NestedLoopJoinBatch_ don't check if
_allocateNew()_ returns false assuming it will throw an exception instead.
