smengcl opened a new pull request, #11506: URL: https://github.com/apache/ozone/pull/11506
Generated-by: Claude Code (Opus 5.5) ## What changes were proposed in this pull request? `TestFailureHandlingByClient#testContainerExclusionWithClosedContainerException` timed out in `waitForContainerClose`, waiting for a container to be present on a datanode. The previous test in the class shut down two datanodes of a pipeline, and `restartDownDataNodes` restarted them. That method only waits for the datanodes to register with SCM, not for their Ratis groups to elect a leader. In the failing run the surviving peer kept failing vote requests to the restarted peers with `UNAVAILABLE: io exception`, so the group had no leader for about 38 seconds. SCM still allocated the test key's first block on that pipeline. The write timed out with `RaftRetryFailureException` and the client moved the data to a new block on another pipeline, but the test read the container ID from `streamEntryList.get(0)`, which was never created on any datanode. The other tests in the class also assume their first block lands on a healthy pipeline, so the fix is in `restartDownDataNodes`: after the cluster is ready, wait until every Ratis group on each restarted datanode has a leader. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-16967 ## How was this patch tested? - Checkstyle clean. - A local run could not be used: on macOS a mini cluster datanode fails its volume check and exits the fork, unrelated to this change. - 10x10 [flaky-test-check](https://github.com/smengcl/hadoop-ozone/actions/runs/38362647581) on this branch: in progress 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
