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

解决方案：

在hive 安装目录下，创建一个临时的IO文件iotmp。比如hive的安装目录是/home/hadoop/app/hive

然后将路径配置到hive-site.xml文件的以下参数中：

< property>
	< name>hive.querylog.location< /name>
	< value>/home/hadoop/app/hive/iotmp< /value>
	< description>Location of Hive run time structured log file< /description>
< /property>
      
< property>
	< name>hive.exec.local.scratchdir< /name>
	< value>/home/hadoop/app/hive/iotmp< /value>
	< description>Local scratch space for Hive jobs< /description>
< /property>
      
< property>
	< name>hive.downloaded.resources.dir< /name>
	< value>/home/hadoop/app/hive/iotmp< /value>
	< description>Temporary local directory for added resources in the remote file system.< /description>
< /property>
