一、HWI安裝

二、其中遇到一些問題：

1.遇到如下問題，將jre環境中的toos.jar 服務到lib目錄下

2.CDH中沒有hwi相關配置參數，手動加入并修改端口為9998，發現并未生效，暫時未找到原因所在。

一、HWI安裝

通過查看《Hadoop權威指南》發現hive有 hwi功能研究一下看看是否方便

執行

[root@test111 lib]# hive --service hwi OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release ls: cannot access /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/lib/hive-hwi-*.war: No such file or directory OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 18/09/21 11:16:03 INFO hwi.HWIServer: HWI is starting up 18/09/21 11:16:03 INFO mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog 18/09/21 11:16:03 INFO mortbay.log: jetty-6.1.26.cloudera.4 18/09/21 11:16:04 INFO mortbay.log: Started SocketConnector@0.0.0.0:9999

訪問鏈接發現根本不是web頁面，媽的。都是文件

后來發現需要編譯相關war包，傳入服務器。?

首先下載相對應的源碼下載地址：http://www.apache.org/dyn/closer.cgi/hive/

進入hwi目錄

apache-hive-1.2.2-src/hwi

編譯成war包?

注意打包方式要使用這種，網上很多種方式，使用完之后發現還不是web操作頁面

jar cvfM0 hive-hwi-1.2.1.war -C web/ .

?查找hive的目錄安裝在

/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hive/lib

?將hive-hwi-1.2.1.war 復制到該目錄下，運行報錯如下

[root@test111 hive]# hive --service hwi OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 18/09/21 11:11:25 INFO hwi.HWIServer: HWI is starting up 18/09/21 11:11:26 ERROR hwi.HWIServer: HWI WAR file not found at /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/lib/hive-hwi-1.1.0.war

?提示文件沒有在目錄中找到，cd進這個目錄發現沒有該目錄，手動創建

[root@test111 hive]# mkdir -p /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/lib/

將文件?hive-hwi-1.2.1.war 也復制到該目錄下

再次執行

[root@test111 lib]# hive --service hwi OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 18/09/21 11:15:00 INFO hwi.HWIServer: HWI is starting up 18/09/21 11:15:00 INFO mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog 18/09/21 11:15:00 INFO mortbay.log: jetty-6.1.26.cloudera.4 18/09/21 11:15:00 INFO mortbay.log: Extract /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/bin/../lib/hive/lib/hive-hwi-1.1.0.war to /tmp/Jetty_0_0_0_0_9999_hive.hwi.1.1.0.war__hwi__.4otk49/webapp 18/09/21 11:15:00 INFO mortbay.log: Started SocketConnector@0.0.0.0:9999

訪問http://192.168.2.111:9999/hwi/? ?一定要加上hwi 否則無法訪問

?

二、其中遇到一些問題：

1.遇到如下問題，將jre環境中的toos.jar 服務到lib目錄下

cp tools.jar /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hive/lib 18/09/21 10:35:21 ERROR mortbay.log: /hwi/hwi/web/ Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK.

2.CDH中沒有hwi相關配置參數，修改端口為9991

CDH中修改配置參數，hive-site相關有很多個配置，修改如圖所示的那個參數，其他的修改無法生效。

hive-site.xml 的 Hive 客戶端高級配置代碼段（安全閥） <property><name>hive.hwi.listen.port</name><value>9991</value><final>true</final> </property>

HWI 簡單使用 參考：https://blog.csdn.net/zhangshenghang/article/details/82800390?
