-------------------------------------
Summary: Interpreters - Need better sharing mode that promotes
code re-usability, modulerizations
Key: ZEPPELIN-2376
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2376
Project: Zeppelin
Issue Type: Improvement
Components: Interpreters, zeppelin-interpreter
Reporter: nirav patel
Priority: Critical
Currently zeppelin interpreter supports shared, scope and isolation mode which
are good at high level but when you have a set of notebook and want to re-use
code none of this are ideal . Here's why
1) shared - compiler treat all interpreter paragraphs across all notebooks as
one unit . This causes overriding of variables with out knowledge (because you
don't get any compile time error; nor paragraph has no ability to compiled and
give user error if variable is already used in other notebook). Hard to debug
problems and requires careful consideration of not duplicating any variables
across notebooks.
2) scope - different compilers for different notebook but now you can't share
code. Everything has to be in one notebook. This doesn't scale well
3) Isolation - NA for this issue.
I think we need ability to import certain notebooks so we can re-use code with
out stepping on someone elses notebook variables.
