----------------------------------------------------------------
I propose this design -
. build/control the classpath internally within code for all the essential jars
that are part and parcel of storm
. designated dir(s) for worker, and for external (contrib and/or 3rd party
integration)
. an optional jars listing file within the dir(s) for orderly sequencing of the
jars in building the classpath further by appending jars to classpath
. within code - check if the jars listing file is present
. if present, read it to append jars to the classpath
. if not present, then get a listing of the jars present in the dir(s), and
append them to the classpath following natural ordering resulting from the
listing
. use of a bootstrap jar to start the base process, do the ground work of
building the classpath from essential jars, and then add to classpath the extra
jars in specified dirs, and finally exec the process based on arg passed that
designates the process to be exec'd

> Proposing a dir (extlib) to hold jars for external (contrib and/or 3rd party
> integration). storm script can first pick up the jars in lib dir for
> classpath, and then the jars in extlib dir.
