如何像其他Linux用户一样提交hadoop作业

概述用户“hadoop”是集群上的runnnig jobtracker和tasktracker,但是如果其他 Linux用户想要提交他们的工作呢？ 我已经按照这个文档,http://hadoop.apache.org/docs/r1.0.4/service_level_auth.html#Hadoop+Services+and+Configuration+Properties 将以下内容添加到“cor 用户“hadoop”是集群上的runnnig jobtracker和tasktracker,但是如果其他 Linux用户想要提交他们的工作呢？

我已经按照这个文档,http://hadoop.apache.org/docs/r1.0.4/service_level_auth.html#Hadoop+Services+and+Configuration+Properties
将以下内容添加到“core-site.xml”中：

<property>            <name>hadoop.security.authorization</name>            <value>true</value>    </property>

对于conf文件“hadoop-policy.xml”,我将“hadoopGroup”添加到“security.job.submission.protocol.acl”,我的帐户“qingya.shu”属于该组.
但当我运行hadoop作为qingya.shu时,遇到如下错误：

请注意,lustre用作分布式文件系统而不是HDFS.

谁能帮我？

解决方法 试试这个：

<property>    <name>hadoop.security.authorization</name>    <value>simple</value>  </property>
