[jira] [Created] (SAMZA-1233) Fix SamzaTaskProxy system admin instantiation

Shanthoosh Venkataraman created SAMZA-1233:
----------------------------------------------

             Summary: Fix SamzaTaskProxy system admin instantiation
                 Key: SAMZA-1233
                 URL: https://issues.apache.org/jira/browse/SAMZA-1233
             Project: Samza
          Issue Type: Task
            Reporter: Shanthoosh Venkataraman
            Assignee: Shanthoosh Venkataraman
            Priority: Minor


SamzaTaskProxy instantiates all SystemAdmin classes defined in 
job configuration. 

This is unnecessary and sometimes leads to ClassNotFoundException when  different SystemAdmin(HdfsSystemAdmin, ElasticSearchAdmin) classes are not available in classpath during samza-rest deployment and introduces library dependency from all system modules (samza-kakfa, samza-hdfs etc)directly into samza-rest. 

To solve this problem, instantiate SystemAdmin for job coordinator alone in SamzaTaskProxy.
