the hadoop user is the runnnig jobtracker and tasktracker on the cluster, but what if other Linux users want to submit their jobs?
I followed this documentation, http://hadoop.apache.org/docs/r1.0.4/service_level_auth.html#Hadoop+Services+and+Configuration+Properties add the following to "core-site.xml":
<property> <name>hadoop.security.authorization</name> <value>true</value> </property>
and for the conf file "hadoop-policy.xml", I add "hadoopGroup" to "security.job.submission.protocol.acl", my account "qingya.shu" belongs to this group. but when I run hadoop as qingya.shu, I encountered an error, for example:

Can anybody help me?
