解决方法：
修改配置文件vi hive-site.xml，将有关${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D的都替换成对应路径，如下：

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