---------------------------------
Summary: Passing parameters from one paragraph to another
Key: ZEPPELIN-3716
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3716
Project: Zeppelin
Issue Type: Improvement
Reporter: Dmitriy
(this is my first ticket, feel free to find wrong things in it and update).
We haven't found a solution for a problem on SOF
([https://stackoverflow.com/questions/51783199/apache-zeppelin-passing-parameters-between-different-interpreters]
), so I propose to have a new feature in Zeppelin.
It will help a lot to have a capability to pass one paragraph's result to
another paragraph as the values of the dropdown list. Example:
I'm building a dashboard in Apache Zeppelin using org.postgresql.Driver to
connect to Greenplum database. Usually I use something like:
{{where country_title like '${country=UK,UK|USA|Canada|%}' }}
to pass parameters into my query. But I have a long list of other parameters
(like "towns") which I also need to pass to my query. And they are different
for different _country_title_ values. I can use something like:
{{select towns from towns_by_country where country_title like
'${country=UK,UK|USA|Canada|%}' }}
to get a list of towns. How can I use it as a parameter in drop-down menu (WITH
'%', of course).
We can use _z.angularBind_ or _z.put_ & _z.get_ , of course. But they work in
_%spark_ interpreters, not in custom interpreters. And custom interpreters for
connecting with DBs are easy and fun to use in Zeppelin.
