16/06/28 12:39:45 ERROR tool.ImportTool: Error during import: Import job failed!問題原因：
因爲Hive底層執行job是hadoop的MP，如果auxService:mapreduce_shuffle不存在，我們就須要配置。
解決方案：
設置yarn-site.xml文件，添加以下內容：
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>*注意：在master和slave所有的主從機器上都需要修改這個文件，修改後重啓即可，不用格式化（hadoop namenode -format）
