Roey Shem Tov commented on FLINK-17469:
---------------------------------------
Adding to this conversation,
i am agree with the second solution [~aljoscha] offers.
Flink need to support more cli application commands (such as -p),
for example --appName or --name can be a good solution over here.
> Support override of DEFAULT_JOB_NAME with system property for
> StreamExecutionEnvironment

> Key: FLINK-17469
> URL: https://issues.apache.org/jira/browse/FLINK-17469
> Project: Flink
> Issue Type: New Feature
> Components: API / DataSet, API / DataStream
> Affects Versions: 1.10.0
> Reporter: John Lonergan
> Priority: Trivial
>
> We are running multiple jobs on a shared standalone HA Cluster.
> We want to be able to provide the job name via the submitting shell script
> using a system property; for example "job.name".
> We could of course write Java application code in each job to achieve this by
> passing the system property value ourselves to the execute(name) method,
> however we want to do this from the env.
> ---
> However, there exists already default job name in
> StreamExecutionEnvironment.DEFAULT_JOB_NAME.
> Our proposed changed to add a method to StreamExecutionEnvironment...
> {code:java}
> String getDefaultJobName() {
> return System.getProperty("default.job.name",
> StreamExecutionEnvironment.DEFAULT_JOB_NAME);
> }
> {code}
> .. and call that method rather than directly accessing
> StreamExecutionEnvironment.DEFAULT_JOB_NAME
> This change is backwards compatible.
> We need this method to evalulate on a job by job basis so for example the
> following small amendment to the existing DEFAULT_JOB_NAME value will NOT
> work because this will not allow us to vary the value job by job.
> {code:java}
> class StreamExecutionEnvironment {
> static final String DEFAULT_JOB_NAME =
> System.getProperty("default.job.name", "Flink Streaming Job"))
> }
> {code}
