-------------------------------
Summary: Improve the state of adaptive sheduler with
StateWithoutExecutionGraph
Key: FLINK-32859
URL: https://issues.apache.org/jira/browse/FLINK-32859
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Reporter: Rui Fan
Assignee: Rui Fan
Currently, most of states of adaptive scheduler are extends
StateWithExecutionGraph, and it can reduce a lots of repeated code.
We can define the State{color:red}Without{color}ExecutionGraph and the
corresponding Context, then the rest of states can extend the
State{color:red}Without{color}ExecutionGraph, such as: Created,
WaitingForResources, CreatingExecutionGraph.
This improvement can reduce a lot of code for these states, such as: cancel(),
suspend(), getJob(), handleGlobalFailure() and getLogger().
These methods of Created, WaitingForResources and CreatingExecutionGraph are
same.
