ambari complains components should be restarted - hive and yarn

[#1]

Hello,

I am seeing error on ambari it says that hive and yarn components needs to be restarted, but I am not seeing any information in ambari agent log or yarn or hive log. How do I find out why we need to restart these comporents?

@Anpan K This probably means you made a change on ambari. Ambari gives you this alert so that you know that new configuration needs to be pushed to the nodes. During restart ambari will push the new configuration to the nodes and the alert will disappear - You should restart when possible.

@Anpan K Usually upon a saved change/new service install ambari will ask you to restart one or more services.

.

Ambari is aware that certain actions performed on service Y will require a restart of service X - Hence marks as restart is required.

.

Why restart is required sometimes requires you to know what have been latest changes performed. Check the services version and see if any changes have been done recently. Or perhaps a new service was added.
