---------------------------------------
Summary: Tests in TestXMLReader use non-deterministic HashMap
Key: NIFI-10862
URL: https://issues.apache.org/jira/browse/NIFI-10862
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);
OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode);
Reporter: Sopan Phaltankar
Assignee: Sopan Phaltankar
Fix For: 1.19.0
{code:java}
1. org.apache.nifi.hbase.TestScanHBase#testScanToContentWithStringValues
2.
org.apache.nifi.hbase.TestScanHBase#testScanToContentWithQualifierAndValueJSON{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}
1. org.apache.nifi.hbase.TestScanHBase.testScanToContentWithStringValues

*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
