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.
