Description

SYMPTOM
With LDAP server which has hundreds of users and groups, Ranger Usersync never finishes the initial sync or takes extremely long time, when Group Search First & Enable User Search both are set to true.
The usersync.log shows similar to below repeatedly.

19 Apr 2018 17:15:19 INFO LdapUserGroupBuilder [UnixUserSyncThread] - Updating username for cn=xxxxx...

 

WORKAROUND:
If deltasync (Incremental Sync) is enabled, do not see this symptom, because LdapUserGroupBuilder calls getUsers() in the for loop, but LdapDeltaUserGroupBuilder doesn't use this method in the loop in updateSink().
