ERROR: DISABLED: Security features are not available

Here is some help for this command:
Show all permissions for the particular user.
Syntax : user_permission <table>

Note: A namespace must always precede with '@' character.

For example:

    hbase> user_permission
    hbase> user_permission '@ns1'
    hbase> user_permission '@.*'
    hbase> user_permission '@^[a-c].*'
    hbase> user_permission 'table1'
    hbase> user_permission 'namespace1:table1'
    hbase> user_permission '.*'
    hbase> user_permission '^[A-C].*'

It seems your hbase:acl table is not created.

can you check hbase-site.xml at master side as well it should have:-

       <property>      
<name>hbase.coprocessor.master.classes</name>    
  <value>org.apache.hadoop.hbase.security.access.AccessController</value>  
  </property>

try restarting your cluster as postStartMaster step should create this table, once you are able to do scan 'hbase:acl' , you will not see above error "ERROR: DISABLED:Security features are not available"

Got the logs from @nshetty and checked somehow the hbase:acl table is not created because earlier hbase:acl znode is present but the table is not present. Once after deleting the hbase:acl table znode and restarting the service it's working fine.
