Hi, John. I get a core dump from the binary kudu server when trying to run the tests. Didn't find a log file, but will search thoroughly later. Happened anytime to you? Does it happens to anyone?
I am using Ubuntu 18.04 Thank you! Regards, Alfonso Nishikawa El dom., 4 ago. 2019 20:10, Furkan KAMACI <furkankam...@gmail.com> escribió: > Hi John, > > I've already made my comments at your PR.
