> 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 them independent of the order of elements returned by the iterator:
> https://github.com/apache/flink/pull/23464
> 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:
