Krishna Anandan Ganesan updated FLINK-33443:
--------------------------------------------
Description:
We are proposing to make the following test stable:
{code:java}
org.apache.flink.connectors.hive.HiveRunnerITCase.testWriteComplexType{code}
*STEPS TO REPRODUCE THE ISSUE:*
# The following command can be run to execute the test with the
[NonDex|https://github.com/TestingResearchIllinois/NonDex] plugin:
{code:java}
mvn -pl flink-connectors/flink-connector-hive
edu.illinois:nondex-maven-plugin:2.1.1:nondex
-Dtest=org.apache.flink.connectors.hive.HiveRunnerITCase#testWriteComplexType
{code}
# The following error will be encountered:
{code:java}
[ERROR] Failures:
[ERROR] HiveRunnerITCase.testWriteComplexType:166
expected: "[1,2,3] {1:"a",2:"b"} {"f1":3,"f2":"c"}"
but was: "[1,2,3] {2:"b",1:"a"} {"f1":3,"f2":"c"}"
[INFO]
[ERROR] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0{code}
*ROOT CAUSE ANALYSIS:*
The test is currently flaky because of the assumption that the order of
elements received in the _result_ variable will be consistent. There are
currently two versions of query output that can be stored in _result._
# The actual order that is expected where the output of the map attribute is
\{1: "a", 2: "b"}.
# The other order is the one shown in the error extract above where the
ordering of the map attribute from the table is \{2: "b", 1: "a"}.
*POTENTIAL FIX:*
* The fix that I can suggest/have ready to raise a PR for is introducing
another assertion on the second variant of the query output.
* By asserting on whether the contents in _result_ are in one of the two
orders, we can ascertain that the expected attributes with their contents are
received as expected should the order in which they are received, not matter.
Please share your thoughts on this finding and let me know if any other
potential fix is possible for this test.
