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:
