Jinglun commented on HDFS-15106:
--------------------------------
Hi [~ayushtkn], thanks your reminding ! The discussion makes sense to me. I
haven't thought overhead for other developers before. I think we should close
this jira, this Jira is not about performance or maintainability.
> Remove unused code from FSDirConcatOp.

> I was reading code about rpc concat() and found an unused variable named
> count. It was originally used to compute the namespace delta. Now we use
> QuotaCounts deltas so it becomes useless. To be clear we should remove it.
