Question

我有 hadoop 1.2.1，我在单个节点上安装了 hive 0.14.0

$ hive

HDFS 上的 root scratch 目录:/tmp/hive 应该是可写的。当前权限为:rwxrwxr-x。

我使用 hadoop fs -chmod g+w/tmp/hive 但不工作。

Answer 1

使用以下命令更新/tmp/hive HDFS 目录的权限

hadoop fs -chmod 777 /tmp/hive

如果可以，您可以删除本地和 hdfs 上的/tmp/hive。

hadoop fs -rm -r /tmp/hive;  
rm -rf /tmp/hive

此位置仅保留临时文件。即使我们删除它也没有问题，将在需要时以适当的权限创建。
