[jira] [Created] (ARROW-2165) enhance AllocatorListener to listen for child allocator addition and removal

Vanco Buca created ARROW-2165:
---------------------------------

             Summary: enhance AllocatorListener to listen for child allocator addition and removal
                 Key: ARROW-2165
                 URL: https://issues.apache.org/jira/browse/ARROW-2165
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java - Memory
            Reporter: Vanco Buca


AllocatorListener allows a BaseAllocator to track when users allocate memory. However, the structure of the users' allocators can't be tracked easily. 

I suggest an enhancement to the AllocatorListener: onNewChild(BufferAllocator) and onChildClosed(BufferAllocator)
