Hi Chris, I got the main cause :)
In my view, the result of netstat is very abnormal because your binding address ip is 127.0.0.1. If so, other machines cannot access your TajoMaster. Your tajo-site looks valid. So, please check two things: - All machines use tajo-site.xml that you attached to this mailing list. - Please ensure restarting your cluster after you set the tajo-site.xml. Probably, you can fix the problem easily if you check above things. Have a nice weekend. - Hyunsik On Fri, Sep 26, 2014 at 12:12 PM, Christian Schwabe <[email protected]> wrote: > > Hello Hyunsik, > > TajoMaster on "Master" MacBook seems to run normally.
