Anatoli Shein commented on HDFS-10740:
--------------------------------------
Thanks for the review, [~James C].
Actually, I don't think this code in fact needs synchronization because this
whole recursion is running in a single thread and futures.push_back is never
executed simultaneously. It basically generates a large number of requests
sequentially one-by-one, and then just goes to wait on all of the responses.
Please let me know if you agree.
