remove yarn.resourcemanager.hostname explicit set

[dreadjr]

I couldn't connect to the YARN UI on port 8088. I am not sure why it is specifically being set. Maybe i am missing something.

netstat -anp | grep 8088

tcp6       0      0 127.0.0.1:8088          :::*                    LISTEN      5378/java

After removing explicit set of yarn.resourcemanager.hostname I was able to access the YARN UI.

netstat -anp | grep 8088

tcp6       0      0 :::8088                 :::*                    LISTEN      8725/java

:+1: looks like the IP address for my ethernet network interface is used in the link for the ApplicationMaster so without this mod the link is hitting an address that isn't listening on that port

This just caught me out too (running in a Vagrant).

Any reason why this hasn't been merged yet?
