Subject [jira] [Commented] (HDFS-10740) libhdfs++: Implement recursive directory generator

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.

> This tool will allow us do benchmarking/testing our find functionality, and will be a
good example showing how to call a large number or namenode operations reqursively.
