Illya Yalovyy commented on OOZIE-2402:
--------------------------------------
No functionality change since previous patch, only style related fixes.
This failed test (.

seems to be irrelevant. I can re-submit my patch if required.

> Copy the tarball itself takes only around 10 seconds. It seems like
> performance could be improved by loading files concurrently in many threads.
