回复：Do we need to kill a spark job every time we change and deploy it?

I think if your job is running and you want to deploy a new jar which is the new version for the other, spark will think the new jar is another job ,
they distinguish job by  Job ID , so if you want to replace the jar ,you have to kil job every time;

主题:  Do we need to kill a spark job every time we change and deploy it?



Hi,

I have a question for you. 
Do we need to kill a spark job every time we change and deploy it to cluster? Or, is there a way for Spark to automatically pick up the recent jar version?



Best regards,
Mina
