shilei-ly created FLINK-38118:
---------------------------------
Summary: The execution.attached=true parameter does not take
effect in application mode
Key: FLINK-38118
URL: https://issues.apache.org/jira/browse/FLINK-38118
Project: Flink
Issue Type: Bug
Components: Client / Job Submission
Affects Versions: 1.20.2, 2.0.0
Reporter: shilei-ly
In FLINK-35625, flink merged the per-job mode and application mode. Currently,
flink1.20 and flink2.x only support application mode, but in application mode,
the *execution.attached=true* and *execution.shutdown-on-attached-exit=true*
parameter has no effect. I think application mode should support these
parameters, because attach mode is very useful in some scenarios, such as using
attach mode in dolphinscheduler scheduler to monitor flink cluster status.
The functions of these parameters are as follows:
1. After submitting the task through {*}flink run -Dexecution.attached=true
xxx.jar{*}, the flink client process keeps running until the application
cluster stops.
2. After submitting the task through {*}flink run -Dexecution.attached=true
-Dexecution.shutdown-on-attached-exit=true xxx.jar{*}, the flink client can
control the life cycle of the application cluster. When ctrl + c stops the
flink client process, the application cluster should stop all jobs and stop the
cluster.
I think we can do this through flink client heartbeat. [~xtsong] [~fcsaky]
[~gaborgsomogyi] Can you give me some suggestions? I want to submit a PR to
fix this bug.
