## Summary `DataNodeMetrics` already tracks `WritesFromLocalClient` / `WritesFromRemoteClient` (count only) and `RemoteBytesRead` / `RemoteBytesWritten` (bytes), but there is no byte-level metric for **local** client reads/writes. This patch adds two new `MutableCounterLong` metrics: | Metric | Description | |---|---| | `LocalBytesRead` | Bytes read by local (same-host) clients | | `LocalBytesWritten` | Bytes written by local (same-host) clients | These are incremented in `incrReadsFromClient(boolean local, long size)` and `incrWritesFromClient(boolean local, long size)` alongside the existing remote-bytes counters, so no call-site changes are required. ## Changes - `DataNodeMetrics.java` — added `localBytesRead` / `localBytesWritten` fields and updated `incrReadsFromClient` / `incrWritesFromClient` to increment them - `TestDataNodeMetrics.java` — added `testLocalBytesMetrics` which spins up a `MiniDFSCluster`, writes then reads a file from the local client, and asserts both new counters are positive while the remote-bytes counters remain zero ## Testing | Test class | Test method | Result | Duration | |---|---|---|---| | `TestDataNodeMetrics` | `testLocalBytesMetrics` | PASSED | 2.391 s | -- This is an automated message from the Apache Git Service.
