Rubik-W opened a new issue #2112: [BUG] many dependent tasks depend on a node, 
task status bug
URL: https://github.com/apache/incubator-dolphinscheduler/issues/2112
 
 
   **Describe the bug**
   When many dependent tasks depend on a node and the dependent task supports 
failed retry, the task that submitted the retry will be judged as kill. causes 
process instance to fail.
   
   I think, no need to verify process strategy when submitting tasks.
   
   The method updateProcessInstanceState of the MasterExecThread class has been 
verify process strategy.
   
   ```
       private void updateProcessInstanceState() {
           ExecutionStatus state = getProcessInstanceState();
           if(processInstance.getState() != state){
   ```
   
   ```
       private ExecutionStatus getProcessInstanceState(){
           ProcessInstance instance = 
processService.findProcessInstanceById(processInstance.getId());
           ExecutionStatus state = instance.getState();
   
           if(activeTaskNode.size() > 0){
               return runningState(state);
           }
           // process failure
           if(processFailed()){
               return ExecutionStatus.FAILURE;
           }
   ```
   
   ```
       private Boolean processFailed(){
           if(hasFailedTask()) {
               if(processInstance.getFailureStrategy() == FailureStrategy.END){
                   return true;
               }
               if (processInstance.getFailureStrategy() == 
FailureStrategy.CONTINUE) {
                   return readyToSubmitTaskList.size() == 0 || 
activeTaskNode.size() == 0;
               }
           }
           return false;
       }
   ```
