i am coming in late to this party, but i think the core issue , how would
the bolt know that the script has changed so it can reload the parser. I was
thinking if the previous bolt could add aversion tag to the raw message.. The
parser bolt compares this version or checksum to the last one it had, if
different reruns init and stores this value into the bolt. Else just drops the
version an processes the raw message. A simple checksum may be. Since the
scripts can be really evolved, we could give user more leverage if we allowed
them to keep in HDFS or a filesystem. even a rest api. Please let me know if i
am way off.
