----------------------------------
Summary: Use LinkedHashMap for deterministic iterations
Key: FLINK-16351
URL: https://issues.apache.org/jira/browse/FLINK-16351
Project: Flink
Issue Type: Bug
Components: Tests
Reporter: testfixer0
The test `testSimple` in `MapBundleOperatorTest` may fail due if `HashMap`
iterates in a different order. Specifically,
`assertThat(Arrays.asList("k1=v1,v2", "k2=v3"), is(func.getOutputs()))` may
fail. `testSimple` depends on `open` in class `AbstractMapBundleOperator`. The
field `bundle` is a `HashMap`. However, `HashMap` does not guarantee any
specific order of entries. Thus, the test can fail due to a different iteration
order.
