Thanks Lee -
It seemed like none of the interpreters started due to a lack permission on
the interpreters.sh file. My bad.

Hi @azurecoder<https://github.com/azurecoder>
Zeppelin runs interpreter as separate process and communicate with it using
thrift protocol.
Connection refused error above is there's some problem between connection
between Zeppelin-daemon and Interpreter process.
To figure out what is causing the error, i recommend do following steps,
1. stop zeppelin if it is running, by bin/zeppelin-daemon.sh
2. check any zeppelin-daemon/zeppelin interpreter process running. If
there're kill them. eg) ps -ef | grep -i zeppelin | grep -v grep | awk '{print
$2}' | xargs kill
3. start zeppelin and try run some code
4. if connection refused error raised, then check
logs/zeppelin-interpreter-[INTERPRETER_NAME]-*.log if there're any exception.
