I think in case the checkpointing is disabled the default strategy should
be `noRestart`.
> Restart strategy defined in flink-conf.yaml is ignored

>
> Key: FLINK-9143
> URL: https://issues.apache.org/jira/browse/FLINK-9143
> Project: Flink
> Issue Type: Bug
> Components: Configuration
> Affects Versions: 1.4.2
> Reporter: Alex Smirnov
> Assignee: yuqi
> Priority: Major
> Attachments: execution_config.png, jobmanager.log, jobmanager.png
>
>
> Restart strategy defined in flink-conf.yaml is disregarded, when user enables
> checkpointing.
> Steps to reproduce:
> 1. Download flink distribution (1.4.2), update flink-conf.yaml:
>
> restart-strategy: none
> state.backend: rocksdb
> state.backend.fs.checkpointdir:
> [file:///tmp/nfsrecovery/flink-checkpoints-metadata]
> state.backend.rocksdb.checkpointdir:
> [file:///tmp/nfsrecovery/flink-checkpoints-rocksdb]
>
> 2. create new java project as described at
> [https://ci.apache.org/projects/flink/flink-docs-release-1.4/quickstart/java_api_quickstart.html]
> here's the code:
> public class FailedJob
> {
> static final Logger LOGGER = LoggerFactory.getLogger(FailedJob.class);
> public static void main( String[] args ) throws Exception
> {
> final StreamExecutionEnvironment env =
> StreamExecutionEnvironment.getExecutionEnvironment();
> env.enableCheckpointing(5000, CheckpointingMode.EXACTLY_ONCE);
> DataStream<String> stream =
> env.fromCollection(Arrays.asList("test"));
> stream.map(new MapFunction<String, String>(){
> @Override
> public String map(String obj)
> { throw new NullPointerException("NPE"); }
>
> });
> env.execute("Failed job");
> }
> }
>
> 3. Compile: mvn clean package; submit it to the cluster
>
> 4. Go to Job Manager configuration in WebUI, ensure settings from
> flink-conf.yaml is there (screenshot attached)
>
> 5. Go to Job's configuration, see Execution Configuration section
>
> *Expected result*: restart strategy as defined in flink-conf.yaml
>
> *Actual result*: Restart with fixed delay (10000 ms). #2147483647 restart
> attempts.
>
>
> see attached screenshots and jobmanager log (line 1 and 31)
