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

             Summary: Cleanup TaskManager initialization logic
                 Key: FLINK-1580
                 URL: https://issues.apache.org/jira/browse/FLINK-1580
             Project: Flink
          Issue Type: Bug
            Reporter: Till Rohrmann


Currently, the TaskManager initializes many heavy load objects upon registration at the JobManager. If an exception occurs during the initialization it takes quite long until the {{JobManager}} detects the {{TaskManager}} failure.

Therefore, it would be better if we could rearrange the initialization logic so that the {{TaskManager}} only registers at the {{JobManager}} if the all objects could be initialized successfully. Moreover, it would be worthwhile to move some of the initialization work out of the {{TaskManager}}.
