-------------------------------

             Summary: Change the de/serialization protocol of LogicalPlan of QueryUnitAttempt
from Json to ProtocolBuffer
                 Key: TAJO-269
                 URL: https://issues.apache.org/jira/browse/TAJO-269
             Project: Tajo
          Issue Type: Task
          Components: master, worker
            Reporter: Jihoon Son
            Assignee: Jihoon Son
             Fix For: 0.3-incubating


In the current implementation, the logical plan is serialized into a JSON object and sent
to each worker.
However, the transmission of JSON object incurs the high overhead due to its large size.
ProtocolBuffer is a good alternative because it's overhead is quite small and already used
in other modules of Tajo.
