我在 hadoop 中创建了配置单元目录：

hadoop fs -mkdir /usr/hive/warehouse

和为表设置权限：

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

但是还是不行？我该怎么办？

Answer 1

HDFS 目录 /tmp/hive 似乎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用户（sudo -su hdfs命令即可），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;

Answer 2

检查 hive-site.xml 上以下标签的值，然后更改提到的文件夹的权限

<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;
