hadoop.security.group.mapping.ldap.bind.user=uid=ldapadmin,ou=people,dc=join,dc=com

hadoop.security.group.mapping.ldap.bind.password=00000

hadoop.security.group.mapping.ldap.base=dc=join,dc=com

hadoop.security.group.mapping.ldap.search.filter.user=(&(objectClass=posixAccount)(uid={0}))

hadoop.security.group.mapping.ldap.search.filter.group=(objectClass=posixGroup)

hadoop.security.group.mapping.ldap.search.attr.member=memberUid

hadoop.security.group.mapping.ldap.search.attr.group.name=cn
