yuanfenghu commented on FLINK-35896:
------------------------------------
When an exception occurs in ScalingRealizer.realizeParallelismOverrides, I
encountered this issue locally, but I couldn't retrieve this exception from the
eventhandler table. The first approach is to catch it in JobAutoScalerImpl.
{code:java}
//代码占位符
try {
scalingRealizer.realizeParallelismOverrides(ctx, userOverrides);
} catch (Exception e) {
eventHandler.handleException(ctx, AUTOSCALER_ERROR, e);
} {code}
The other approach is to handle it separately in RescaleApiScalingRealizer, but
I prefer the former
> eventHandler in RescaleApiScalingRealizer handle the event of scaling failure
