-------------------------------------
Summary: Remove flakiness from tests in
OperatorStateBackendTest.java
Key: FLINK-33156
URL: https://issues.apache.org/jira/browse/FLINK-33156
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.17.1
Reporter: Asha Boyapati
Fix For: 1.17.1
This issue is similar to:
https://issues.apache.org/jira/browse/FLINK-32963
We are proposing to make the following tests stable:
{quote}org.apache.flink.runtime.state.OperatorStateBackendTest#testSnapshotRestoreSync
org.apache.flink.runtime.state.OperatorStateBackendTest#testSnapshotRestoreAsync{quote}
The tests are currently flaky because the order of elements returned by
iterators is non-deterministic.
The following PR fixes the flaky test by making it independent of the order of
elements returned by the iterator:

We detected this using the NonDex tool using the following commands:
{quote}mvn edu.illinois:nondex-maven-plugin:2.1.1:nondex -pl flink-runtime
-DnondexRuns=10
-Dtest=org.apache.flink.runtime.state.OperatorStateBackendTest#testSnapshotRestoreSync
mvn edu.illinois:nondex-maven-plugin:2.1.1:nondex -pl flink-runtime
-DnondexRuns=10
-Dtest=org.apache.flink.runtime.state.OperatorStateBackendTest#testSnapshotRestoreAsync{quote}
Please see the following Continuous Integration log that shows the flakiness:
