69.2 操作演示
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

[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
安装Spark2
- 下载csd文件：
http://archive.cloudera.com/spark2/csd/SPARK2_ON_YARN-2.1.0.cloudera1.jar
- csd文件移动至/opt/cloudera/csd目录下
[root@ip-186-31-6-148csd]# pwd

[root@ip-186-31-6-148 csd]#
csd目录如不存在，则创建
[root@ip-186-31-6-148cloudera]# mkdir csd
[root@ip-186-31-6-148 cloudera]# chown cloudera-scm:cloudera-scm csd/
- 重启CM服务
[root@ip-186-31-6-148~]# service cloudera-scm-serverrestart
Stopping cloudera-scm-server: [ OK ]
Starting cloudera-scm-server: [ OK ]
