Hi Jungtaek I had to move to a different server and can't reproduce the same issue anymore. I can now see the 'start' option on the UI.
I had to modify the *flight.bash* script as $JAVA_HOME is undefined, this yields */usr/share/apache-storm-1.2.1/bin/flight.bash: line 62: /bin/jstack: No such file or directory* however, the files can be found in the default path */usr/bin* I will submit a PR so that the script checks that $JDKPATH is not empty and exist before using it for BINPATH. I can't see any downsides in doing so.
