-----------------------------------
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);

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
