[jira] [Created] (REEF-1140) MonotonicTreeMap used in Class Hierachy should be thread safe for reading.

Julia created REEF-1140:
---------------------------

             Summary: MonotonicTreeMap used in Class Hierachy should be thread safe for reading. 
                 Key: REEF-1140
                 URL: https://issues.apache.org/jira/browse/REEF-1140
             Project: REEF
          Issue Type: Bug
          Components: Tang.NET
            Reporter: Julia
            Priority: Minor


ClassHierarchy wraps MonotonicTreeMap as an internal data structure. Currently it has a lock for adding a node. However, if a threading is adding a node while another thread is iterating the children, that could cause issue. We should make read thread safe as well.
