             Summary: [Java] VectorSchemaRoot should be able to be closed() more than once
                 Key: ARROW-1283
                 URL: https://issues.apache.org/jira/browse/ARROW-1283
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java - Vectors
            Reporter: Bryan Cutler
            Assignee: Bryan Cutler


When working with a VectorSchemaRoot, once it is no longer needed it resources are freed by calling {{close()}} followed by then closing the allocator.  Sometimes it is needed to close a second time due to complex operations.  If the VectorSchemaRoot is closed again after the allocator, it raises an assertion error during {{clear()}} because it is trying to allocate an empty buffer.  The {{close()}} operation should mean that the object is no longer to be used, so this empty buffer is not needed and ends up being destroyed immediately anyway.
