Description

When multiple users share a zeppelin instance, it is sometimes desirable to use the same interpreter with different settings.

It should be possible an administrator to setup some of the Interpreter settings as overridable by setting a place holder and a default value
It should be possible for a user to specify the actual values via properties.

An example,

For JDBC interpreter, common.max_count specifies the maximum number of rows to displayed.

We can configure it to be overridden by users using max_rows property as follows:

Change interpreter settings common.max_count = ${max_rows,100}

If the user using the interpreter has not specified a value for max_rows, then the default value of 100 will be used.

The user can set property by going to the Properties menu and adding a new property.

set max_rows=500
