---------------------------------
Summary: Remove YARN magic properties file
Key: FLINK-15470
URL: https://issues.apache.org/jira/browse/FLINK-15470
Project: Flink
Issue Type: Task
Components: Command Line Client, Deployment / YARN
Reporter: Yang Wang
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|https://issues.apache.org/jira/browse/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.
