-------------------------------------
Summary: Race condition in all *ConfOption classes
Key: GIRAPH-1069
URL: https://issues.apache.org/jira/browse/GIRAPH-1069
Project: Giraph
Issue Type: Bug
Reporter: Sergey Edunov
Assignee: Sergey Edunov
*ConfOption classes, such as ClassConfOption, IntConfOption, FloatConfOption
etc, call AllOtions.add(this) from their constructor. This call updates static
list without any synchronization. Hence, if you create conf option classes in
different threads you run into race condition.
The only reason we have AllOptions is to create documentation. It can be done
with reflection instead. So, let's remove AllOtions.add(this) from all conf
classes and implement reflection based approach in AllOptions
