启用hive hwi方法

hive启动hwi：
./hive --service hwi
ls: cannot access /opt/cdh-5.3.6/hive-0.13.1/lib/hive-hwi-*.war: No such file or directory
17/05/12 09:29:47 INFO hwi.HWIServer: HWI is starting up
17/05/12 09:29:48 INFO mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog
17/05/12 09:29:48 INFO mortbay.log: jetty-6.1.26.cloudera.4
17/05/12 09:29:48 INFO mortbay.log: Started SocketConnector@0.0.0.0:9999

从日志可以看到启动hwi报错：cannot access /opt/cdh-5.3.6/hive-0.13.1/lib/hive-hwi-*.war: No such file or directory
这时因为没有hive-hwi-*.war这个包，这里我们需要手工编译这个包：
下载hive源码包：hive-0.13.1-cdh5.3.6-src.tar.gz
解压后进入源码包hwi目录下，执行以下打包命令将hwi目录打成war包：
$sudo jar cvfM0 hive-hwi-0.13.1.war -C web/ .

adding: img/glyphicons-halflings-white.png(in = 4352) (out= 4352)(stored 0%)
将打包后的war包cp到hive/lib目录下：
cp hive-hwi-0.13.1.war /opt/cdh-5.3.6/hive-0.13.1/lib/

在hive-site.xml文件中配置hive-hwi包路径：

<property>
         <name>hive.hwi.war.file</name>
         <value>lib/hive-hwi-0.13.1.war</value>
     </property>
    
启动hive hwi，通过web登录http://host:port/hwi，报错如下：

com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/opt/java/jdk1.7.0_67/jre"
    
解决办法：

cp /opt/java/jdk1.7.0_67/lib/tools.jar /opt/cdh-5.3.6/hive-0.13.1/lib/

然后再次登录成功。

hive hwi相关参数：

./hive -e "set" |grep hive.hwi.listen
hive.hwi.listen.host=0.0.0.0
hive.hwi.listen.port=9999

hive.hwi.war.file=lib/hive-hwi-0.13.1.war
