CM添加kafka服务

下载所需的包：

在http://archive.cloudera.com/kafka/parcels/latest/ 选择合适parcel下载：

ubuntu14.04的cdh5.5.1对应包

http://archive.cloudera.com/kafka/parcels/latest/KAFKA-2.0.0-1.kafka2.0.0.p0.12-trusty.parcel

http://archive.cloudera.com/kafka/parcels/latest/KAFKA-2.0.0-1.kafka2.0.0.p0.12-trusty.parcel.sha1

http://archive.cloudera.com/kafka/parcels/latest/manifest.json

在http://archive.cloudera.com/csds/kafka/ 下载

http://archive.cloudera.com/csds/kafka/KAFKA-1.2.0.jar

在cm server主机：

mv KAFKA-1.2.0.jar  /opt/cloudera/csd/KAFKA-1.2.0.jar
mv KAFKA-2.0.0-1.kafka2.0.0.p0.12-trusty.parce* /opt/cloudera/parcel-repo/
mv manifest.json /opt/cloudera/parcel-repo/

进入网页：http://ha0:7180

菜单栏–主机–parcel–检查新的parcel–分配–激活

如果启动时出现内存溢出错误

在kafka配置中修改Java Heap Size of Broker 512即可
