Kudu安装

Kudu的Parcel部署
- 下载Kudu的Parcel包：

http://archive.cloudera.com/kudu/parcels/5.12.1/KUDU-1.4.0-1.cdh5.12.1.p0.10-el6.parcel
http://archive.cloudera.com/kudu/parcels/5.12.1/KUDU-1.4.0-1.cdh5.12.1.p0.10-el6.parcel.sha1
http://archive.cloudera.com/kudu/parcels/5.12.1/manifest.json

以上面文件下载到http服务所在服务器的/var/www/html/kudu1.4目录

[root@ip-186-31-6-148~]# cd /var/www/html/
[root@ip-186-31-6-148 html]# mkdir kudu1.4

[root@ip-186-31-6-148 kudu1.4]#

Kudu服务安装
- CM界面配置Kudu的Parcel地址，并下载，分发，激活Kudu
- 选择Master和Tablet Server
- 配置相应的目录，无论是Master还是Tablet根据实际情况，数据目录(fs_data_dir)应该都可能有多个，以提高并发读写，从而提高Kudu性能
配置Impala
- 在Impala的高级配置项中设置KuduMaster的地址和端口：

--kudu_master_hosts=ip-186-31-6-148.fayson.com:7051

多个master可以以“,”分割如：

--kudu_master_hosts=ip-186-31-6-148.fayson.com:7051,ip-186-31-6-148.fayson.com:7051

Kafka服务安装
- CM配置Kafka的Parcel包地址并保存
- Kafka选择一组依赖关系
- 选择Kafka Broker和Gateway
- 根据集群环境修改Kafka配置
- 修改Kafka Broker的heap大小，默认为50M，可能会导致Kafka启动失败

向topic发送消息

[root@ip-186-31-6-148hive]# kafka-console-producer--broker-list ip-186-31-10-118.fayson.com:9092 --topic test

消费topic的消息

[root@ip-186-31-6-148hive]# kafka-console-consumer --zookeeperip-186-31-6-148.fayson.com:2181 --topic test --from-beginning

查看topic描述信息

[root@ip-186-31-6-148hive]# kafka-topics --describe--zookeeper ip-186-31-6-148.fayson.com:2181 --topic test
