interpreter-setting.json properties
Hello,
I'm doing task https://issues.apache.org/jira/browse/ZEPPELIN-922 (introducing new interpreter registration mechanism for Scalding) and I have a question about interpreter-setting.json.
Why do we need "propertyName"? It always has the same value as a key in properties map (or null). I can't find any usages of it in code.
Should I add this property to new json or just omit it?
Thank you
Igor Drozdov

Hi,
Thanks for explaining it. It was used to support old one and new one. Not
all interpreter are initialized by interpreter-setting.json thus we should
keep both of them. After we move to new mechanism fully, we need to talk to
modify those structures.

Hi JL,
I think Igor means the property name appears twice in the
interpreter-setting.son
E.g. In the following setting, zeppelin.livy.url appears twice.
"zeppelin.livy.url": {
"envName": "ZEPPELIN_LIVY_HOST_URL",
"propertyName": "zeppelin.livy.url",
"defaultValue": "http://localhost:8998",
"description": "The URL for Livy Server."
},
Best Regard,
Jeff Zhang

Hi,
Zeppelin supports two way to pass the configuration to interpreter.
propertyName is one of these way to do. I don't know what you talk about
exactly but interpreter's properties map is initialized by set of
propertyNames in interpreter-setting. If you remove propertyName, those key
are not initialized when the interpreter starts.
