-----------------------------------
Summary: 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
Affects Versions: 1.4.2
Reporter: Alex Smirnov
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.
see attached screenshots and jobmanager log (line 1 and 31)
