             Summary: TestHttpFlowFileServerProtocol.testTransferTwoFiles is a Flaky Test
                 Key: NIFI-10622
                 URL: https://issues.apache.org/jira/browse/NIFI-10622
             Project: Apache NiFi
          Issue Type: Bug
          Components: NiFi Registry
         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: Yiteng Zhang
             Fix For: 1.18.0
         Attachments: org.apache.nifi.remote.protocol.http.TestHttpFlowFileServerProtocol.txt

 
{code:java}
org.apache.nifi.remote.protocol.http.TestHttpFlowFileServerProtocol.testTransferTwoFiles {code}
This test can pass the maven-test. However, it shows non-deterministic behavior under [NonDex|[https://github.com/TestingResearchIllinois/NonDex]]'s test and thus failed. 

 

The test result is below:

 
{code:java}
[ERROR] Errors:  [ERROR]   TestHttpFlowFileServerProtocol.testTransferTwoFiles:411 » IO StandardHttpFlowFileServerProtocol[CommsID=testTransferTwoFiles] Sent data to peer Peer[url=http://peer-host:8080/] but calculated CRC32 Checksum as 2668300945 while peer calculated CRC32 Checksum as 3058746557; canceling transaction and rolling back session {code}
It seems like two peers calculate a different checksum, therefore the transaction was rolled back, and thus the test failed.

*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
