> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Environment: Apache Maven 3.6.0;
> openjdk version "1.8.0_342";
> OpenJDK Runtime Environment (build 1.8.0_342-8u342-b07-0ubuntu1~20.04-b07);

> This is a flaky test, it can pass mvn test while but when run using the tool
> [NonDex|https://github.com/TestingResearchIllinois/NonDex], it fails. NonDex
> is a tool that will introduce non-determinism in certain java collections.
> The test shows below:

> *Steps to reproduce the failure:*
> # Run the following command in nifi:
> # First, build the module:
> {noformat}
> mvn install -pl nifi-nar-bundles/nifi-hbase-bundle/nifi-hbase-processors
> -DskipTests -Drat.skip -am{noformat}
> # Then run the test using
> [NonDex|https://github.com/TestingResearchIllinois/NonDex]
> {noformat}
> 1. mvn -pl nifi-nar-bundles/nifi-hbase-bundle/nifi-hbase-processors
> edu.illinois:nondex-maven-plugin:1.1.2:nondex
> -Dtest=org.apache.nifi.hbase.TestScanHBase#testScanToContentWithStringValues
> 2. mvn -pl nifi-nar-bundles/nifi-hbase-bundle/nifi-hbase-processors
> edu.illinois:nondex-maven-plugin:1.1.2:nondex
> -Dtest=org.apache.nifi.hbase.TestScanHBase#testScanToContentWithQualifierAndValueJSON{noformat}
>
> The result will be saved under the module folder in .nondex
