@patsevanton I had the same Problem, modified the Makefile and now it works. Here is my version:

.PHONY: rpm clean source

SCALA_VERSION ?= 2.12
VERSION = $(shell echo $(KAFKA_VERSION) | sed "s/-/_/")

SOURCE_NAME = kafka_$(SCALA_VERSION)-$(KAFKA_VERSION)
SOURCE = $(SOURCE_NAME).tgz
TOPDIR = /tmp/kafka-rpm
PWD = $(shell pwd)

METRICS_GRAPHITE_URL = http://search.maven.org/remotecontent?filepath=com/yammer/metrics/metrics-graphite/2.2.0/$(METRICS_GRAPHITE)

You may have to modify it to suit your needs
