----------------------------------
Summary: a single user created twice when creating default policy
and usersync process syncs user at the same time,and got 404 http code when
retrive service policies
Key: RANGER-2416
URL: https://issues.apache.org/jira/browse/RANGER-2416
Project: Ranger
Issue Type: Bug
Components: admin
Affects Versions: 0.6.0
Environment: in hdp ambari 2.6
Reporter: zhangxiong
a single user created twice when creating default policy and usersync process
syncs user at the same time,and got 404 http code when retrive service policies.
the two concurrent processes creating the same user at the same time:
1)where create a service repository like kafka, ranger admin will create a
default policy for the user kafka.if the user kafka doesn't exists,ranger admin
would create the user first.
2)ranger usersnc process syncs user kafka from ldap.
if the above two process happens nearly the same time,the user will be create
twice in the ranger admin side.as a result,ranger admin db's x_user table got
two record for the user kafka,as shown below:
mysql> select id,added_by_id,user_name,descr from x_user where
user_name='kafka' or id=2 or id=27;
+----+-------------+----------------+-------------------------------+
| id | added_by_id | user_name | descr |
+----+-------------+----------------+-------------------------------+
| 2 | NULL | rangerusersync | rangerusersync |
| 27 | 2 | ambari-qa | ambari-qa - add from Unix box |
| 28 | 27 | kafka | kafka
|
|29|2 |kafka |kafka - add from Unix box |
in this situation,if we search policies for service kafka,we got 404 http
code,.this caused by XXUserDao's error for getting singleResult.
getEntityManager()
.createNamedQuery("XXUser.findByUserName", XXUser.class)
.setParameter("name", name.trim())
.getSingleResult();
the command for search policies:
curl -i -H 'Authorization:Basic YW1iX3Jhbmdlcl9hZG1pbjphbWJhcmkxMjM=' -H
'Accept:application/json' -H 'Content-Type:application/json'
