我在hadoop中创建了配置单元目录：

hadoop fs -mkdir /usr/hive/warehouse

并设置表的权限：

hadoop fs -chmod g+w /usr/hive/warehouse

但还是不起作用？我该怎么办？

hadoop Hive

看起来hdfs目录/tmp/hive丢失或没有足够的权限在其中写入文件。执行以下命令以分配适当的权限。
先切换到hdfs admin user( sudo -su hdfs 命令），然后执行以下命令。

hadoop fs -chmod 777 /tmp;
hadoop fs -mkdir /tmp/hive;
hadoop fs -chmod -R 777 /tmp/hive;

检查hive-site.xml上下面标记的值，然后更改所述文件夹的权限

<property>
<name>hive.exec.local.scratchdir</name>
<value>/tmp/mydir</value>
<description>Local scratch space for Hive jobs</description>
</property>

hadoop fs -rmr /tmp/mydir;
hadoop fs -mkdir /tmp/mydir;
hadoop fs -chmod 777 /tmp/mydir;
hadoop fs -chmod -R 777 /tmp/mydir;
