-----------------------------------

             Summary: Several Related Flaky Tests in TestHttpClient
                 Key: NIFI-10623
                 URL: https://issues.apache.org/jira/browse/NIFI-10623
             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.client.http.TestHttpClient.txt

These tests:
{code:java}
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTP
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTPS
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTPSWithProxy
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTPSWithProxyAuth
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTPWithProxy
org.apache.nifi.remote.client.http.TestHttpClient.testSendLargeFileHTTPWithProxyAuth
org.apache.nifi.remote.client.http.TestHttpClient.testSendSuccessWithProxyAuth
org.apache.nifi.remote.client.http.TestHttpClient.testSendSlowClientSuccess
org.apache.nifi.remote.client.http.TestHttpClient.testSendSuccessCompressed{code}
can pass using the normal maven-test, but show non-deterministic behaviors under [NonDex|[https://github.com/TestingResearchIllinois/NonDex]] and thus failed.

An example of the error message is below:
{code:java}
[ERROR] Errors: 
[ERROR]   TestHttpClient.testSendLargeFileHTTPS:1024->testSendLargeFile:954->testSendIgnoreProxyError:940 » IO Failed to confirm transaction with Peer[url=https://localhost:33385/nifi-api] due to java.io.IOException: [Url=https://localhost:33385/nifi-api, TransferDirection=SEND, State=DATA_EXCHANGED] Sent data to peer Peer[url=https://localhost:33385/nifi-api] but calculated CRC32 Checksum as 2387509971 while peer calculated CRC32 Checksum as 1527414060; 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}

      3. the result will be saved under the package folder in .nondex
h4.
