一、下载hive-src.tar
[hadoop@hftest0001 ~]$ pwd /home/hadoop [hadoop@hftest0001 ~]$ wget [hadoop@hftest0001 ~]$ tar -zxvf apache-hive-1.2.1-src.tar.gz [hadoop@hftest0001 hwi]$ cd /home/hadoop/apache-hive-1.2.1-src/hwi [hadoop@hftest0001 hwi]$ pwd /home/hadoop/apache-hive-1.2.1-src/hwi [hadoop@hftest0001 hwi]$ jar cfM hive-hwi-1.2.1.war -C web . [hadoop@hftest0001 hwi]$ cp hive-hwi-1.2.1.war /home/hadoop/apache-hive-1.2.1-bin/lib/
二、启动 troubleshooting
[root@hftest0001 apache-hive-1.2.1-bin]# pwd /home/hadoop/apache-hive-1.2.1-bin [root@hftest0001 apache-hive-1.2.1-bin]# ./bin/hive --service hwi 16/01/25 09:37:25 INFO hwi.HWIServer: HWI is starting up 16/01/25 09:37:27 FATAL hwi.HWIServer: HWI WAR file not found at /home/hadoop/apache-hive-1.2.1-bin/home/hadoop/apache-hive-1.2.1-bin/lib/hive-hwi-1.2.1.war [root@hftest0001 apache-hive-1.2.1-bin]# 系统默认会找/home/hadoop/apache-hive-1.2.1-bin/home/hadoop/apache-hive-1.2.1-bin/lib/hive-hwi-1.2.1.war，多了目录 修改配置文件，使用绝对路径 [root@hftest0001 apache-hive-1.2.1-bin]# vi conf/hive-site.xml ... ...hive.hwi.listen.host 10.224.246.232 hive.hwi.listen.port 9999 [root@hftest0001 apache-hive-1.2.1-bin]# ./bin/hive --service hwi 16/01/25 09:37:25 INFO hwi.HWIServer: HWI is starting up 16/01/25

系统还是会找/home/hadoop/apache-hive-1.2.1-bin/home/hadoop/apache-hive-1.2.1-bin/lib/hive-hwi-1.2.1.war，多了目录 即不能使用绝对路径，要使用相对路径 [root@hftest0001 apache-hive-1.2.1-bin]# vi conf/hive-site.xml ... ...
