[jira] [Updated] (RANGER-2088) If not deltasync (Incremental Sync)
enabled, getUsers is called too many times
[ https://issues.apache.org/jira/browse/RANGER-2088?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Velmurugan Periasamy updated RANGER-2088:
-----------------------------------------
Fix Version/s: (was: 2.0.0)
> If not deltasync (Incremental Sync) enabled, getUsers is called too many times
> ------------------------------------------------------------------------------
>
> Key: RANGER-2088
> URL: https://issues.apache.org/jira/browse/RANGER-2088
> Project: Ranger
> Issue Type: Bug
> Components: usersync
> Affects Versions: 0.7.0
> Reporter: Hajime Osako
> Assignee: Sailaja Polavarapu
> Priority: Major
>
> *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.
> {noformat}
> 19 Apr 2018 17:15:19 INFO LdapUserGroupBuilder [UnixUserSyncThread] - Updating username for cn=xxxxx...
> {noformat}
>
> *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().
