在使用hive的时候启动成功
[root@localhost bin]# ./hive

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
在执行查询函数时却提示错误
hive> show functions;
OK
Failed with exception java.io.IOException:java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:user.name%7D
Time taken: 1.171 seconds
解决
将conf下面的hive-site.xml文件中的所有的system:user.name替换成用户名称，猜测可能是我使用的root管理员的情况下出现
替换后再次重启hive，执行show funcitons;成功
hive> show functions;
OK

可以看到错误元在system:user.name的配置。
关联找到hive-site.xml里面，将{system:user.name}改为你的用户名，
同时也可以将iotmp的对应配置修改成真实地址。
${system:java.io.tmpdir} 改为真实物理路径。
