CDH- Hive HWI 配置
目录
一、HWI安装
二、其中遇到一些问题：
1.遇到如下问题，将jre环境中的toos.jar 服务到lib目录下
2.CDH中没有hwi相关配置参数，手动加入并修改端口为9998，发现并未生效，暂时未找到原因所在。
一、HWI安装
通过查看《Hadoop权威指南》发现hive有 hwi功能研究一下看看是否方便
执行
[root@test111 lib]# hive --service hwi

后来发现需要编译相关war包，传入服务器。
首先下载相对应的源码下载地址：http://www.apache.org/dyn/closer.cgi/hive/
进入hwi目录
apache-hive-1.2.2-src/hwi编译成war包
注意打包方式要使用这种，网上很多种方式，使用完之后发现还不是web操作页面
jar cvfM0 hive-hwi-1.2.1.war -C web/ .查找hive的目录安装在
/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hive/lib将hive-hwi-1.2.1.war 复制到该目录下，运行报错如下

再次执行

访问http://192.168.2.111:9999/hwi/ 一定要加上hwi 否则无法访问
二、其中遇到一些问题：
1.遇到如下问题，将jre环境中的toos.jar 服务到lib目录下

CDH中修改配置参数，hive-site相关有很多个配置，修改如图所示的那个参数，其他的修改无法生效。
hive-site.xml 的 Hive 客户端高级配置代码段（安全阀）
hive.hwi.listen.port
9991
true
