anuengineer commented on issue #1349: HDDS-2026. Overlapping chunk region cannot be read concurrently URL: https://github.com/apache/hadoop/pull/1349#issuecomment-525509862 bq. But in Ozone world, a chunk once written is immutable , and hence we might not need the lock at all while reading a chunk. In the cblock work, we added a flag that can be used to overwrite the block. so this current patch is safer.
