如何使用glusterfs-hadoop插件？

Question

我安装了glusterfs并且工作正常，之后我安装了Hadoop1.x并且可以很好地使用hdfs，但是当我使用glusterfs-hadoop插件来使用glusterfs作为我的hadoop的文件系统后端时，我得到了错误，我使用github站点来安装glusterfs-hadoop插件。并将jar文件复制到hadoop库目录，并将我的core-site.xml更改为：

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>

<property>
<name>fs.glusterfs.impl</name>
<value>org.apache.hadoop.fs.glusterfs.GlusterFileSystem</value>
</property>

<property>
<name>fs.default.name</name>
<value>glusterfs://fedora1:9010</value>
</property>

<property>
<name>fs.AbstractFileSystem.glusterfs.impl</name>
<value>org.apache.hadoop.fs.local.GlusterFs</value>
</property>

<property>
<name>fs.glusterfs.volumes</name>
<value>test1</value>
</property>

<property>
<name>fs.glusterfs.volume.fuse.test1</name>
<value>/mnt/Hadoop</value>
</property>

</configuration>

当执行start-mapred.sh时，jobtracker和tasktracker start会忽略任何问题，但当执行以下命令"hadoop fs -mkdir ossl“时，我会得到以下输出：

请帮帮我，谢谢你的回复。

如果我没记错的话，这应该是可行的：

<property>
  <name>fs.default.name</name>
  <value>glusterfs:///fedora1:9010</value>
</property>
