> Key: FLINK-12502
> URL: https://issues.apache.org/jira/browse/FLINK-12502
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination, Tests
> Affects Versions: 1.9.0
> Reporter: Till Rohrmann
> Assignee: leesf
> Priority: Major
>
> The {{JobMasterTest#testRequestNextInputSplitWithDataSourceFailover}} relies
> on how many files you have in your working directory. This assumption is
> quite brittle. Instead we should explicitly instantiate an
> {{InputSplitAssigner}} with a defined number of input splits.
> Moreover, we should make the assertions more explicit: Input split
> comparisons should not rely solely on the length of the input split data.
> Maybe it is also not necessary to capture the full
> {{TaskDeploymentDescriptor}} because we could already know the producer's and
> consumer's {{JobVertexID}} when we create the {{JobGraph}}.
