Yang Wang commented on FLINK-15470:
-----------------------------------

[~tison] Yes, it may break some users running Flink on Yarn in the following 
condition. So we need to take a serious consideration.

 Start a Flink session and then submit the session without `-yid` cli option. 
Then Flink client will try to find a proper Yarn properties files to retrieve 
the existing cluster.
{code:java}
./bin/yarn-session.sh
./bin/flink run ./examples/batch/WordCount.jar{code}
 

If the users are submitting with `yid`, it works just as before.

> Remove YARN magic properties file

> Currently, when we start a session, flink client will write a yarn properties 
> under \{java.io.tmpdir}/.yarn-properties-\{user-name}. So the user could use 
> a simple command {{./bin/flink run ./examples/batch/WordCount.jar}} to submit 
> a job to the session.
>  
> Even if the session cluster has finished or kill by {{yarn application 
> -kill}}, it will still submit a job to the non-existing session. Some users 
> has run into this problem in the ML. So i suggest to remove the properties 
> file and always use {{-yid application_id}} to submit job an existing session.

> We also have some discussion under FLINK-15179. The cli options will be 
> deprecated in the future and we hope {{FlinkYarnSessionCli}} could use 
> {{ExecutorCli}}. So we will try to clean up the code, i think the magic 
> properties file is the case.
