METRON-950: Migrate storm-kafka-client to 1.1 ## Contributor Comments There are MAJOR performance issues with the storm-kafka-client. Throughput is roughly an order of magnitude faster in the 1.1.0 version vs the 1.0.3. This also removes the requirement for the non-HDP profile to rely on the HDP repo. I will point out that the storm-kafka-client in 1.1 does rely on `Time.nanoTime()`, a method call that was introduced in 1.1. To get around this, I've created the `metron-storm-kafka-override` with a backported implementation of the `Time` class. This will be removed when we migrate to Storm 1.1. Normally, I would hold off this change until we take the effort to migrate to 1.1 properly, but the combination of empirical evidence (I saw it go an order of magnitude slower in 1.0.1 vs 1.1) and wide ranging change for Storm 1.1 makes me err on the side of getting this in faster. It should help make every topology faster, but is in particular absolutely required to get sensible throughput in the pcap topology. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
