Hadoop-2.6.0 Authorization not working for MR jobs

Question

• I have configured hadoop-2.6.0 with kerberos security.
• For authorization, i referred the Documentation. But security.job.submission.protocol.acl property is not available in the hadoop-policy.xml.
• It seems the property changed into security.job.client.protocol.acl. Even though i add any of these property for submitting map reduce jobs, its not working.
• Any user can submit the map reduce job. How to authorize the particular user or group to submit the MR jobs.

Property

<property>
    <name>security.job.client.protocol.acl</name>
    <value>kumar</value>
    <description>ACL for MRClientProtocol, used by job clients to
    communciate with the MR ApplicationMaster to query job status etc. 
    The ACL is a comma-separated list of user and group names. The user and
    group list is separated by a blank. For e.g. "alice,bob users,wheel".
    A special value of "*" means all users are allowed.</description>
</property>

Answer 1

I found the answer in the cloudera Documentation here

It seems that the property security.job.client.protocol.acl is for MR1 and for MR2 we can use security.applicationclient.protocol.acl.
