How to pass zeppelin interpreter properties ?

[Ashwin Shankar <as...@gmail.com>]

Hi,
I want to set some zeppelin interpreter properties like "presto.url"
to a default value when I start zeppelin, so that users don't have to
manually specify it on the "Interpreter" page on the UI.
How do I set defaults on those properties ?

PS: I tried passing it as "-D" when I start zeppelin. I also tried setting
it
in zeppelin-site.xml. Both didnt work.

Thanks,
Ashwin

Thanks moon. For presto interpreter, it looks like it doesn't read from
system properties at all(-D), it reads only from what is saved on
"interpreter page"(?). Basically it might be nice if interpreters work in a
way such that user's don't have to configure properties on the interpreter
page, and just read from whatever admin sets,.

Hi,

Behavior of reading property is depends on particular interpreter
implementation.

But most interpreter, currently implemented to first check property value
saved in "Interpreter" page. That's why -D is not overriding / changing
value.

Some interpreter is implemented in the way user can override default value
of interpreter property value by passing -D. In this case, -D overrides
default value but not override once interpreter property is being saved and
read from interpreter.json.

Thanks,
moon
