[~gjy], from another side, we can analysis this issue only from the code.
When some scene happends and the call the +MiniDispatcher#jobNotFinished+
method, it means the flink job terminate unexpectedly, so it will notify the RM
to kill the yarn application with +ApplicationStatus.UNKNOWN+ state, then the
+UNKNOWN+ state will transfer to +{{UNDEFINED}}+ by
+YarnResourceManager#getYarnStatus.+
But, in hadoop system, the +{{UNDEFINED}}+ means the application has not yet
finished.
*MiniDispatcher#jobNotFinished*
{code:java}
@Override
protected void jobNotFinished(JobID jobId) {
super.jobNotFinished(jobId);
// shut down since we have done our job
jobTerminationFuture.complete(ApplicationStatus.UNKNOWN);
}
{code}
*YarnResourceManager#getYarnStatus*
{code:java}
private FinalApplicationStatus getYarnStatus(ApplicationStatus status) {
if (status == null) {
return FinalApplicationStatus.UNDEFINED;
}
else {
switch (status) {
case SUCCEEDED:
return FinalApplicationStatus.SUCCEEDED;
case FAILED:
return FinalApplicationStatus.FAILED;
case CANCELED:
return FinalApplicationStatus.KILLED;
default:
return FinalApplicationStatus.UNDEFINED;
}
}
}
{code}
