How does user user jar conflict resolved in spark interpreter?

[Serega Sheypak <se...@gmail.com>]

Hi zeppelin users!
I have the question about dependencies users are using while running
notebooks using spark interpreter.

Imagine I have configured spark intepreter.

Two users write their spark notebooks.
the first user does

z.load("com:best-it-company:0.1")


the second one user adds to his notebook:

z.load("com:best-it-company:0.2")

Then they start to execute two notebooks concurrently.
What will happen to dependencies?
They have same classes... will spark isolate 0.1 version from 0.2 version
somehow?

You can try mode isolated per user which would create one jvm for each
user.
Check this link for details.
