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

             Summary: Move State Backend Initialization from "registerInputOutput()" to "invoke()"
                 Key: FLINK-3085
                 URL: https://issues.apache.org/jira/browse/FLINK-3085
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 0.10.0
            Reporter: Stephan Ewen
             Fix For: 1.0.0


The state backend initialization currently happens in the {{StreamTask}} in {{registerInputOutput()}}.
For better error handling, it should be part of {{invoke()}}, where the task is properly interrupted,
threads are properly joined, and exceptions are treated aware of cancelling.
