Bugs: RANGER-3806
https://issues.apache.org/jira/browse/RANGER-3806
Repository: ranger
Description
-------
**Problem Statement:**
Ranger db table `x_group_users` has columns "added_by_id" and "upd_by_id" which
should be filled with the id of logged-in user. Whenever group's-users mapping
is pushed from usersync module at that time these values are considered from a
config "ranger.xuser.createdByUserId" which is set to 1 in
ranger-default-admin-site.xml and code as well.
If users have set ranger db table's primary key's auto-increment offset to any
number other than 1 and have not updated the same accordingly in the config
"ranger.xuser.createdByUserId" then request may fail due to Foreignkey
constraint violation.
Example Case: if primary key's auto-increment start value has been set to 2 in
db engine then first entry in table x_portal_user will have primary-key id 2.
while if config "ranger.xuser.createdByUserId" is set to 1 then due to non
availablity of userID 1 when it will try to insert group-user mappinng entry in
`x_group_users` table with value 1 for the column "added_by_id" and "upd_by_id"
it will cause to fail the request.
**Proposed solution:** Rather directly putting the config's
"ranger.xuser.createdByUserId" value in "added_by_id" and "upd_by_id" field of
`x_group_users` table we can check whether user id exist in x_portal_user or
not. if it does not exist then do not set the value received from config
"ranger.xuser.createdByUserId" and avoid the Foreign-key Constraint Violation
Exception.
