Hi Park, Thank you for response to this. I thought that was caused in your pointing at the first, but the py4j had already been installed in it. I guessed the issue of depending on PATH or CLASSPATH environment parameters as well. They were not.
Indeed, it worked fine on other our Linux machine. I am not sure yet what was wrong on the first Linux that was my best dev-machine. :-b Now i have been starting it to be clean-install on the new environment. I would like to share this issue if it will be clear. -Keiji 2017-09-01 12:35 GMT+09:00 Park Hoon <1am...@gmail.com>: > Hi, I haven't used net installation version.
