hive执行查询出现：Error while making MR scratch directory - check filesystem解决办法
进入 $hadoop_home vi conf/core-site.xml
之前的配置是hdfs://192.168.10.145:9060
但是在hive命令行下面查询一直出错：错误信息如下：
FAILED: Hive Internal Error: java.lang.RuntimeException(Error while making MR scratch directory - check filesystem config (null))

改动后:
<property>
??? <name>fs.default.name</name>
??? <value>hdfs://zgz-test-a:9060/</value>
??? <description>The name of the default file system.? A URI whose

</property>
重新启动hadoop，登录hive
