Mkdirs 无法创建 hadoop.tmp.dir

我已经从 Apache Hadoop 0.20.2 升级到最新的稳定版本； 0.20.203。在这样做的同时，我还正确更新了所有配置文件。但是，我在尝试通过 JAR 文件运行作业时遇到以下错误：

$ hadoop jar myjar.jar
$ Mkdirs failed to create /mnt/mydisk/hadoop/tmp

其中 /mnt/mydisk/hadoop/tmp 是 hadoop.tmp.dir 的位置> 如 core-site.xml 中所述：

..
<property>
  <name>hadoop.tmp.dir</name>
  <value>/mnt/mydisk/hadoop/tmp</value>
</property>
..

我已经检查该目录是否存在，并且用户 hadoop 的权限设置是否正确。我还尝试删除该目录，以便 Hadoop 本身可以创建它。但这没有帮助。

使用 hadoop 版本 0.20.2 执行 Hadoop 作业是开箱即用的。然而，更新后有些东西被破坏了。有人可以帮我找出问题所在吗？

I have upgraded from Apache Hadoop 0.20.2 to the newest stable release; 0.20.203. While doing that, I've also updated all configuration files properly. However, I am getting the following error while trying to run a job via a JAR file:

$ hadoop jar myjar.jar
$ Mkdirs failed to create /mnt/mydisk/hadoop/tmp

where /mnt/mydisk/hadoop/tmp is the location of hadoop.tmp.dir as stated in the core-site.xml:

..
<property>
  <name>hadoop.tmp.dir</name>
  <value>/mnt/mydisk/hadoop/tmp</value>
</property>
..

I've already checked that the directory exists, and that the permissions for the user hadoop are set correctly. I've also tried out to delete the directory, so that Hadoop itself can create it. But that didn't help.

Executing an Hadoop job with hadoop version 0.20.2 worked out of the box. However, something is broken after the update. Can someone help me to track down the problem?
