    [ https://issues.apache.org/jira/browse/AMBARI-25065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16729319#comment-16729319 ] 

Akhil S Naik commented on AMBARI-25065:
---------------------------------------

This issue is related to AMBARI-23342 ,

After the fix of AMBARI-23342 , ambari-web is not querying for server for autofill but fetches every data while on start.

we should restrict the API to 20 commands in that case.

> If number of users are more than 20 then it shows only 20 users list. for other user it shows as not present.
> Steps to reproduce:
> 1. Create more than 20 users in Ambari
> 2. Go to File views and start typing the random username under 'Grant permission to these users' - for some it show red mark when try to save it.
> Root cause:
> UI is making REST API call to load only 20 users
> http://172.25.33.6:8080/api/v1/users?Users/user_name.matches(.*.*)&from=0&page_size=20&_=1545350079963
> so Ambari is returning 20 users and rest of them will not shown in views grant page.
