I tried to solve the proxy problem by adding `-Dhttp.proxyHost` and
`-Dhttp.proxyPort` to `JAVA_OPTS` in `bin/zeppelin-daemon.sh`. After doing
this, npm and node were installed without any problems, but zeppelin server
doesn't start and it just hangs after the following log statements. The only
work arounds I can think of are,
1. Removing the proxy options so that node and npm are not installed
2. Create `conf/helium.json` for which I do not know the format
