-------------------------------------

             Summary: setting setNumberOfExecutionRetries to 0 still leads to 
RESTARTs.
                 Key: FLINK-3410
                 URL: https://issues.apache.org/jira/browse/FLINK-3410
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 1.0.0
            Reporter: Robert Metzger


While testing the RC0 for 1.0.0 I found the following issue:

Setting the number of retries to 0 still leads to the job being restarted:

{code}
final StreamExecutionEnvironment see = 
StreamExecutionEnvironment.getExecutionEnvironment();
see.setNumberOfExecutionRetries(0);
{code}

{code}
21:19:50,677 INFO  org.apache.flink.runtime.jobmanager.JobManager               
 - Status of job 0e78d0825da485167aabee7e63c8e913 (Data Generator) changed to 
RESTARTING.
21:19:50,678 INFO  
org.apache.flink.runtime.executiongraph.restart.FixedDelayRestartStrategy  - 
Delaying retry of job execution for 10000 ms ...
{code}

While looking through the code, it seems that the execution config is returning 
{{null}} when the number of retries is set to 0. With {{null}} the jobManager 
picks the default restart strategy.
