by ADMIN 63 views

Introduction

In the realm of software development, Continuous Integration (CI) plays a vital role in ensuring the quality and reliability of code. However, when a test fails, it can be a significant setback for developers. In this article, we will delve into the issue of the DataNodeRequestSenderIT test testSearchWhileRelocating failing in the CI pipeline. We will explore the reproduction line, applicable branches, failure history, and the issue reasons behind this failure.

Reproduction Line

To reproduce the issue, you can run the following command in your terminal:

./gradlew ":x-pack:plugin:esql:internalClusterTest" --tests "org.elasticsearch.xpack.esql.plugin.DataNodeRequestSenderIT.testSearchWhileRelocating" -Dtests.seed=6E659E9470C944B3 -Dtests.locale=saq-Latn-KE -Dtests.timezone=America/Inuvik -Druntime.java=24

This command will run the testSearchWhileRelocating test in the DataNodeRequestSenderIT class, using the specified seed, locale, timezone, and runtime Java version.

Applicable Branches

The applicable branches for this issue are:

  • main

This means that the issue is relevant to the main branch of the repository.

Failure History

Failure Message

The failure message for this issue is:

java.lang.AssertionError: Leftover exchanges ExchangeService{sinks=[2WaEirY7R_-mDsixX5UkdQ:2681/132]} on node node_s1

This message that there are leftover exchanges on the node node_s1, which is causing the test to fail.

Issue Reasons

The issue reasons behind this failure are:

  • [main] 4 failures in test testSearchWhileRelocating (7.3% fail rate in 55 executions)
  • [main] 3 failures in step part-3 (8.1% fail rate in 37 executions)
  • [main] 3 failures in pipeline elasticsearch-pull-request (7.9% fail rate in 38 executions)

These failure rates indicate that the test is failing consistently across different branches and pipelines.

Conclusion

In conclusion, the DataNodeRequestSenderIT test testSearchWhileRelocating is failing in the CI pipeline due to leftover exchanges on the node node_s1. The issue reasons behind this failure are consistent across different branches and pipelines. To resolve this issue, developers should investigate the cause of the leftover exchanges and take necessary steps to fix the issue.

Recommendations

Based on the analysis, the following recommendations can be made:

  • Investigate the cause of the leftover exchanges on the node node_s1.
  • Take necessary steps to fix the issue and prevent leftover exchanges in the future.
  • Review the test code and ensure that it is correctly handling exchanges and node connections.
  • Consider implementing additional testing to ensure that the test is robust and reliable.
