Subject [jira] [Created] (FLINK-1580) Cleanup TaskManager initialization logic
Date Wed, 18 Feb 2015 16:59:11 GMT
Till Rohrmann created FLINK-1580:

             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}}.
