             Summary: Set EvaluationContext once in the TransformEvaluatorFactory instead of forApplication
                 Key: BEAM-608
                 URL: https://issues.apache.org/jira/browse/BEAM-608
             Project: Beam
          Issue Type: Improvement
          Components: runner-direct
            Reporter: Thomas Groh
            Assignee: Thomas Groh
            Priority: Minor


Remove the EvaluationContext parameter from TransformEvaluatorFactory.forApplication() and move it to TransformEvaluatorRegistry.defaultRegistry(), and pass it to all of the TransformEvaluatorFactories created in that constructor.

A single EvaluationContext is produced per pipeline run. TransformEvaluatorFactories are also produced once per pipeline run, as they are stateful (especially with regards to sources). This change will both ensure that Evaluators cannot be reused across pipelines, and cleans up the signature of the TransformEvaluatorFactory interface.
