This is very easy. I've just found soon before.
You can create an additional interpreter from "+Create" button on "Interpreters" screen. If you want to create one more "livy" interpreter, choose "livy" from "Interpreter group". And then I can enable the additional livy interpreter by clicking the interpreter in "Interpreter binding" menu on a notebook that you want to use the interpreter on.

What should I set to an "entity" access policy? As far as I tried, Atlas requires an "entity" access policy defined in Ranger must be "*". If I set other than "*" for "entity", Atlas says "You are not authorized for READ on [ENTITY] : *". I thought I can set the name of an entity like Hive table name to a value of an "entity" access policy. Is this incorrect?

What does "Recovery Host" do in Ambari 2.6.2.2? I found "Recovery Host" in "Host Actions". I learned that this functionality is enabled if all the components on the host are stopped. And then, after stopping all the components and click "Recovery Host", the confirmation window appeared and it shows "This action will completely re-install all components on this host." What does "completely re-install" mean? Additionally, as far as I tried, nothing happened when I clicked "Yes" on the confirmation window.

"NameNode Service RPC Queue Latency (Hourly)" and "NameNode Service RPC Queue Latency (Hourly)" are "UNKNOWN".
Both alerts show "Service RPC port is not enabled.", but NameNodes are running without problems. (NameNodes are configured HA.)
Do I have to ignore these alerts?
But If possible, I want to turn these alerts to "OK".

Thanks, @Jay Kumar SenSharma You mean, for example, even if Metrics Collector is dead from 9 am to 11 am, after Metrics Collector recovers, Metrics Collector will receive all metrics from 9 am to 11 am, right?

Do Metrics Monitor and HadoopTimelineMetricsSink retain metrics to emit while MetricsCollector is dead? Or, discard them? If retaining metrics, how long?
