Asha Boyapati updated FLINK-33156:
----------------------------------
Description:
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:
https://github.com/asha-boyapati/flink/actions/runs/6193757385
Please see the following Continuous Integration log that shows that the
flakiness is fixed by this change:
