我已经在hadoop中创建了hive目录：

hadoop fs -mkdir /usr/hive/warehouse

和设置表的权限：

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

但它还没有用？我该怎么办？

Answer 1

看起来HDFS目录/ tmp / hive丢失或者没有足够的权限来写入文件。执行以下命令以分配适当的权限。

首先切换到HDFS管理员用户（可以使用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;

Answer 2

检查hive-site.xml上以下标记的值，然后更改所提及文件夹的权限

<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;

我有hadoop 1.2.1并且hive为0.14.0
