------------------------------------
Summary: Retrieving execution plan fails succeeding execution
attempt
Key: FLINK-6296
URL: https://issues.apache.org/jira/browse/FLINK-6296
Project: Flink
Issue Type: Bug
Components: DataSet API, Job-Submission, YARN
Affects Versions: 1.2.0
Reporter: Petr Novotnik
Hello,
calling {{ExecutionEnvironment#getExecutionPlan()}} prior to
{{ExecutionEnvironment#execute()}} makes the later fail with the following
message if I try to run my job on yarn, i.e. {{flink run -m yarn-cluster ...}}:
{noformat}
> Caused by: java.lang.RuntimeException: No new data sinks have been defined
> since the last execution. The last execution refers to the latest call to
> 'execute()', 'count()', 'collect()', or 'print()'.

{noformat}
It works fine when executing the job locally (and it works fine locally or even
on yarn using the DataStream API, i.e. {{StreamExecutionEnvironment}}).
So far I could track it down, the problem seems the "clearing" behaviour of
{{ContextEnvironment#createProgramPlan(..)}}. This makes me wonder why
{{#getExecutionPlan}} uses the one parameter version of
{{#createProgramPlan(..)}}. Is "clearing" the sinks really required as part of
{{getExecutionPlan()}}?
I just check, in Flink 1.1.5, {{#getExecutionPlan(..)}} invokes
{{#createProgramPlan("unnamed job", false)}}, hence, it would be good to
document as a breaking change [in the migration
guide|https://ci.apache.org/projects/flink/flink-docs-release-1.2/ops/upgrading.html]
since the resulting error message is rather misleading.
