> Key: FLINK-9143
> URL: https://issues.apache.org/jira/browse/FLINK-9143
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.4.2
> Reporter: Alex Smirnov
> 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|tel:(214)%20748-3647] restart attempts.
