DHIS2 2.30 - Metadata import App shows busy sign and does not recover

Hello,

I am new to dhis environment and struggling to use meta data import feature in version 2.30. I am basically trying to create organization unit under an existing parent. The file only contains two elements parents and name but yet it does not work. When I import the csv file a busy signs pops up and never goes away.

tomcat log shows:

* WARN 2018-08-09 02:53:59,639 No mapping found for HTTP request with URI [/api/29/metadata/csvImportClasses] in DispatcherServlet with name ‘webapi’ (DispatcherServlet.java [http-nio-8080-exec-16])

I found the jira issue https://jira.dhis2.org/browse/DHIS2-4274 that mention issues regarding meta data import but I downloaded the latest 2.30 build from jenkin server and still found problem remains.

Does anyone knows a way around, creating 100+ facilities manually is not going to work for my case.

Regards,

Jamil
