Yiteng Zhang created NIFI-10623: ----------------------------------- 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
