I'm very new to zeppelin.
I have just downloaded zeppelin-0.8.1-bin-all from official mirror on my windows 10 machine.
However, when I execute ./bin/zeppelin.cmd, nothing happened also port 8080 is still closed.
After I found a culprit that is closing curly brace(`}`) which is supposed to be closing parenthesis(`)`) right after `set ZEPPELIN_JMX_PORT="9996"` in commom.cmd.
After I changed correctly, it works.
For now, I found it had been corrected on master branch now.
