@anandsubbu Thanks for contributing this! The only thing I'm unsure of
after reviewing this is your comment regarding this belonging in
parser_master.py or not. On one hand, you could make a case that this is a
parser like any other with the exception that it is spout-only. On the other
hand, we don't currently provide a mechanism (iirc) to start/stop/manage the
PCAP topology from Ambari. Starting parsers doesn't start PCAP, does it?
It may be that PCAP deserves its own "master", e.g. pcap_master.py, and
lifecycle as a proper first class citizen (topology) within Ambari. Below is
the current list of components, and PCAP is not in it afaik, even as a parser
(there's a start_pcap_topology.sh script that is NOT the same as
start_parser_topology.sh). It seems like if we're going to add this to Ambari
we should also provide the ability to manage it. What do you think of that
approach?
