Bryan Cutler updated ARROW-1283:
--------------------------------
Description: 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, which ends up being destroyed immediately anyway. The
{{close()}} operation should mean that the object is no longer to be used, so
once closed it should not try to reallocate it. (was: When working with a
