[jira] [Created] (FLINK-26628) Use REST program arguments in StatefulFunctionsJob

["Fil Karnicki (Jira)" <ji...@apache.org>]

Fil Karnicki created FLINK-26628:
------------------------------------

             Summary: Use REST program arguments in StatefulFunctionsJob
                 Key: FLINK-26628
                 URL: https://issues.apache.org/jira/browse/FLINK-26628
             Project: Flink
          Issue Type: Improvement
          Components: Stateful Functions
            Reporter: Fil Karnicki


Currently the Program Arguments passed into the REST api don't get used by StreamingExecutionEnvironment in StatefulFunctionsJob (in this case the checkpointing will not be set)
{code:java}
--execution.checkpointing.interval 1000 --state.backend rocksdb --state.checkpoint-storage filesystem --state.checkpoints.dir file:///tmp/ --statefun.embedded true {code}
Conversely, Flink CLI params *do* get used by the StreamingExecutionEnvironment in statefun jobs
{code:java}
flink run -Dexecution.checkpointing.interval=1000 -Dstate.backend=rocksdb -Dstate.checkpoint-storage=filesystem -Dstate.checkpoints.dir=file:///tmp/ -Dstatefun.embedded=true myjar.jar{code}
 

To reproduce,
 # clone and run mvn package on [https://github.com/FilKarnicki/statefun-flinkjob/tree/argsNotUsedViaRest]
 # run docker-compose up in flinkjob/docker-compose
 # observe checkpointing happening for this job
 # go to [http://localhost:8081/#/submit] and submit flinkjob-1.0-SNAPSHOT.jar again manually from target with program arguments

{code:java}
 --execution.checkpointing.interval 1000 --state.backend rocksdb --state.checkpoint-storage filesystem --state.checkpoints.dir file:///tmp/ --statefun.embedded true   {code}
        5. observe no checkpointing happening for the second job
