> Key: NIFI-10592
> URL: https://issues.apache.org/jira/browse/NIFI-10592
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Yanni Zhou
> Priority: Minor
> Fix For: 1.16.3
>
>
> The tests below were found flaky because of the use of HashMaps and HashSet.
> The orders of elements in the HashMaps and HashSet are not the same every
> time being called. In this case, LinkedHashMap and LinkedHashSet is applied
> to replace Hash in order to ensure the orders are not changing.
> *org.apache.nifi.reporting.prometheus.TestPrometheusRecordSink.testSendData*
> *org.apache.nifi.reporting.azure.loganalytics.TestAzureLogAnalyticsProvenanceReportingTask.testAddField2*
> *org.apache.nifi.distributed.cache.server.map.DistributedMapCacheTest.testSubMap*
> It matters to fix this flaky test as it may cause potential issues due to the
> uncertainty of orders from HashMaps and HashSet rather than the program
> itself.
