oozie 3.0.2 failing to submit jobs to hadoop 0.20.2

[jabirahmed]

i have added these to my core-site.xml on jt an nn and restarted them

    <property>
            <name>hadoop.proxyuser.oozie.groups</name>
            <value>*</value>
            <description>Allow the superuser oozie to impersonate

any members of the group group1 and group2


hadoop.proxyuser.oozie.hosts
oozie.host1.com,oozie.host2.com
The superuser can connect only from host1
and host2 to impersonate a user

in oozie-site.xml i disabled kerberos

oozie is running as the user oozie and the sample aggregator job runs
fine when i submit it as oozie but fails when i try to submit as
anyother user
