I am not able to spin-up the Full Dev environment with this. It keeps failing here. Have you run this up in Full Dev?

@nickwallen It's my bad I dint run this up in Full Dev, I verified my scripts on a 12 node cluster. I did the required changes to support the Full dev deploymwnt and updated the pull request.

[nickwallen]

Can you merge this with master? It is hard to tell what is part of this PR.

[nickwallen]

The configuration elements for PCAP are still under Metron > Configs > REST. Now that you've added stop/start, I think it would make sense to pull those out into its own component/panel, like the other topologies.

I was able to spin it up, start the pcap topology, throw some pcap at it, and see it get archived in HDFS, then search for that pcap in the UI. So ya for that!

[MohanDV]

@nickwallen having separate panel for PCAP configs is been addressed in the pull request 1132. It will be a duplicate effort here.

[nickwallen]

@MohanDV ... pull request 1132. It will be a duplicate effort here.

Gotcha. I was not aware of the other PR. That will work.

[nickwallen]

+1 Looks great. Thanks a bunch for the contribution.

[nickwallen]

I want to hold off on the merge until we get the pcap properties change sorted on this. @anandsubbu is opening a re-opening a PR on that.

Hi @nickwallen , I would like to create a fresh pull request based on these changes. Could you go ahead and merge this please ?
