I executed the same test on my windows pc and macbook, seems on the windows there's high possibility of failing while on the mac it always pass. It also seems on windows it is quite slow, after discussion with Mike I think probably on windows the merging is slower so that more files are kept open, and thus reaches the limit.
I'll try increase the limit and see how it goes On Mon, Jul 25, 2022 at 10:35 AM Patrick Zhai <zhai7...@gmail.com> wrote: > Seems the error was thrown from HandleLimitFS.java, which enforce an > artificial limitation on the number of files opened it seems.
