{code:java}
org.apache.nifi.hbase.TestHBase_2_ClientService.testScan{code}
This is a flaky test, it can pass maven-test while showing non-deterministic behavior under [NonDex|[https://github.com/TestingResearchIllinois/NonDex]] and thus failed.

The test shows below:
{code:java}
[ERROR] Failures: 
[ERROR]   TestHBase_2_ClientService.testScan:432->verifyResultCell:497 expected: <greeting> but was: <name> {code}
*Steps to reproduce the failure:*
 # install [NonDex|https://github.com/TestingResearchIllinois/NonDex]
 # run the following command in nifi: 
{code:java}
MODULE=nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-site-to-site 

TEST=org.apache.nifi.remote.protocol.http.TestHttpFlowFileServerProtocol#testTransferTwoFiles 

mvn install -pl $MODULE -am -DskipTests 

mvn -pl $MODULE edu.illinois:nondex-maven-plugin:1.1.2:nondex -Dtest=$TEST{code}

 # the result will be saved under the package folder in .nondex
