啓動hive hwi服務時出現 HWI WAR file not found錯誤

./hive --service hwi

[niy@niy-computer /]$ $HIVE_HOME/bin/hive --service  hwi
13/04/26 00:21:17 INFO hwi.HWIServer: HWI is starting up
13/04/26 00:21:18 FATAL hwi.HWIServer: HWI WAR file not found at /usr/local/hive/usr/local/hive/lib/hive-hwi-0.12.0-SNAPSHOT.war

可以看出/usr/local/hive/usr/local/hive/lib/hive-hwi-0.12.0-SNAPSHOT.war 肯定 不是正確路徑，真正路徑是/usr/local/hive/lib/hive-hwi-0.12.0-SNAPSHOT.war

斷定是配置的問題

解決辦法

將hive-default.xml中關於 hwi的設置拷貝到hive-site.xml中即可

<property>
  <name>hive.hwi.war.file</name>
  <value>lib/hive-hwi-0.12.0-SNAPSHOT.war</value>
  <description>This sets the path to the HWI war file, relative to ${HIVE_HOME}. </description>
</property>

<property>
  <name>hive.hwi.listen.host</name>
  <value>0.0.0.0</value>
  <description>This is the host address the Hive Web Interface will listen on</description>
</property>

<property>
  <name>hive.hwi.listen.port</name>
  <value>9999</value>
  <description>This is the port the Hive Web Interface will listen on</description>
</property>

再次運行上面的命令

[niy@niy-computer hive]$ bin/hive --service hwi
13/04/26 00:24:51 INFO hwi.HWIServer: HWI is starting up
13/04/26 00:24:51 INFO mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog

這時打開瀏覽器，輸入

http://localhost:9999/hwi

即可驗證服務已正常開啓
