## What changes were proposed in this pull request? `ReconContainerMetadataManagerImpl#getPipelines(ContainerKeyPrefix)` builds a nested `Stream` pipeline to collect the `Pipeline`s for a key's block locations, but both `.stream().map(...)` calls are intermediate operations with no terminal operation attached. Because Java streams are lazily evaluated, the `pipelines.add(...)` is never actually executed, so the method unconditionally returns the empty `ArrayList` created at the top of the method. This method is the only implementation backing `ContainerMetadataIterator#next()`, which is used by `ReconContainerMetadataManager#getContainersIterator()`. That iterator feeds two REST endpoints in `ContainerEndpoint`: `GET /containers/mismatch` and `GET /containers/mismatch/deleted`. Both currently return `"pipelines": []` for every container, even when the container's key actually has valid pipeline data in OM. This PR replaces the two dangling `.stream().map(...)` chains with `.forEach(...)` ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-16253 ## How was this patch tested? - Ran the existing `TestReconContainerMetadataManagerImpl`: 15/15 tests pass. -- This is an automated message from the Apache Git Service.
