[jira] [Created] (SAMZA-901) SamzaAppState re-design and bug fixes

Jagadish created SAMZA-901:
------------------------------

             Summary: SamzaAppState re-design and bug fixes
                 Key: SAMZA-901
                 URL: https://issues.apache.org/jira/browse/SAMZA-901
             Project: Samza
          Issue Type: Bug
            Reporter: Jagadish


There are a bunch of state data structures that are publicly exposed in SamzaAppState. These must be made thread-safe into accessors. These public global variables could mutated everywhere in Samza without regard for safety/visibility or correctness. 

Making the SamzaAppState thread-safe will fix these races in code. 

For example, there is an integer containerCount that is public which is manipulated by both the metrics reporter and the callback threads.
