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

             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.
