Thx, have changed the settings as below: grep 'read.timeout' /etc/ambari-server/conf/ambari.properties views.ambari.request.read.timeout.millis=520000 views.request.read.timeout.millis=520000 The issue still exists, this is what I get from Ambari: Unable to get list of Slider Apps due to issues below.
Possible reasons include incorrect or invalid view parameters.
Please contact administrator for setting up proper view parameters and verifying necessary services are working.

Hello, I'm setting up Ambari slider view in Ambari 2.5.0 on HDP 2.6.
The Sider view configuration when HDP is my cluster name:
ambari.server.url = http://<ambari_machine>:8080/api/v1/clusters/HDP
ambari.server.username/ambari.server.password = admin/admin
slider.user=${username} When opening this Slider view from Ambari as admin user I get the following error message:
Unable to initialize Slider view: java.net.SocketTimeoutException: Read timed out When checking the log file in /var/log/ambari-server/slider-view I see the following:

When a different XML use, I'm encountering a different issue now - FlowFile Repository Failed to update. Not sure if the InferAvroSchema is mature enough to process bigger json files?
