Summary: Harden
JobMasterTest#testRequestNextInputSplitWithDataSourceFailover
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
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}}.
