sardell edited a comment on issue #1575: METRON-2335: [UI] Implement synchronization between browser user state and Hbase user state URL: https://github.com/apache/metron/pull/1575#issuecomment-565151301 I tested all of the user settings you mentioned with full dev and everything works great from a user's perspective. This is great work, but, of course, I have a few follow up questions/observations. 🙂 * I noticed that every time we are making a POST request to HDFS with the settings you listed above, we are making two http requests. Why is that? * I noticed that when I initially load the page and click on the settings icon, I'm seeing the two http calls mentioned previously even though I haven't made any configuration changes yet. The first call returns with a 500 status and the other returns 200. This only happens the first time I click on the settings icon after a page load. Both calls are to the same endpoint with what appears to be the same request payload.
