The `assertNotNull` wrappers were dropped in an earlier commit on this branch, which left bare `getContainer(...)` calls whose result went unused right after a `queuePushAndWaitForContainer(...)` that had already confirmed presence via `hasContainer`. That commit removes those leftover calls. The two `getContainer(...)` calls that remain both use the return value. ########## hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/ozone/container/replication/TestPerVolumePushReplication.java: ########## @@ -0,0 +1,526 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.

This thread reads as outdated but the issue was still present, so it is worth answering. The failure wait and the assertion now use `supervisor.getReplicationFailureCount(ReplicationTask.METRIC_NAME)` instead of the cluster wide counter, so unrelated SCM driven work on the same datanode can no longer satisfy the condition on its own. The expected failure case additionally asserts that `hasContainer(target, containerOnVol0)` is false, which is the container specific check you suggested, and the success path already polls until the target datanode actually holds the container. ########## hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/ozone/container/replication/TestPerVolumePushReplication.java: ########## @@ -0,0 +1,545 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.

Addressed in 66bf80e1221. The decommission test now asserts the one path `TestDecommissionAndMaintenance` cannot reach. Once the node reaches `DECOMMISSIONED`, SCM sends `SetNodeOperationalState`, the handler calls `supervisor.nodeStateUpdated`, and the per volume pools resize to `scaleOutOfServiceLimit(PER_VOLUME_STREAMS)`. The test waits for every volume pool on that datanode to reach that size, so it fails with the feature off (no per volume pools exist to resize) and it fails if the resize path breaks. The other two tests had the same gap. They now capture `ThreadPoolExecutor.getCompletedTaskCount()` on the pool of the volume that holds the container, push, and wait for that specific counter to advance. So a push served entirely by the global pool no longer passes. `VolumeReplicationThreadPools#getExecutor` is package private and this test shares the package, so this needed no production change. -- This is an automated message from the Apache Git Service.
