java relativepath_Hive启动时，报错RelativepathinabsoluteURI:${system:java.io.tmpdir}

一．启动Hadoop后运行Hive时出现如下错误。

Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D

Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException:

二．错误分析。

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
