Anu Engineer commented on HDDS-2372:
------------------------------------
> Thanks Anu Engineer for the suggestion. Writing to the actual chunk file may
> lead to handling truncation log entries in Ratis inside Ozone which we don't
> need to handle right now as we always write to tmp chunk files
That is correct. That is one of the reasons why we did the tmp way. But that
time we did not have the Data Scrubber thread. Now we do that a data scrubber
thread, so it is trivial for the chunkfile to be detected as junk and cleaned
up by this thread.
