Hive启动时，报错Relative path in absolute URI: ${system:java.io.tmpdir}

一．启动Hadoop后运行Hive时出现如下错误。

三．错误修改。

修改 hive-site.xml 中所有包含 ${system:Java.io.tmpdir} 字段的
value 即路径（vim下 / 表示搜索，后面跟你的关键词，比如搜索 hello，则为 /hello ,
再回车即可），你可以自己新建一个目录来替换它，例如 /home/hive/iotmp . 

我这边把hive-site.xml中所有出现${system:Java.io.tmpdir}的地方都替换成了：

/Users/eleme/Documents/ProgramFiles/apache-software-foundation/apache-hive-2.1.1-bin/iotmp
