{code:java}
org.apache.nifi.hbase.TestHBase_1_1_2_ClientService.testScan{code}
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:
{code:java}
[ERROR] Failures: 
[ERROR]   TestHBase_1_1_2_ClientService.testScan:432->verifyResultCell:497 expected: <greeting> but was: <name> {code}
*Steps to reproduce the failure:*
 # Run the following command in nifi:
 # First, build the module:

{noformat}
mvn install -pl nifi-nar-bundles/nifi-standard-services/nifi-hbase_1_1_2-client-service-bundle/nifi-hbase_1_1_2-client-service -DskipTests -Drat.skip -am {noformat}

 # Then run the test using [NonDex|https://github.com/TestingResearchIllinois/NonDex]

{noformat}
mvn -pl nifi-nar-bundles/nifi-standard-services/nifi-hbase_1_1_2-client-service-bundle/nifi-hbase_1_1_2-client-service edu.illinois:nondex-maven-plugin:1.1.2:nondex -Dtest=org.apache.nifi.hbase.TestHBase_1_1_2_ClientService#testScan{noformat}

 # The result will be saved under the module folder in .nondex
