Object is not a member of a package notebook.io

Object is not a member of a package notebook.io

this is a collision with the relative import option in Scala.
You can normally do:

import foo.bar
import bar.Beer // resolves to foo.bar.Beer

And it's dependent of the declaration order.
It's possible that behind the scenes there's an import for notebook.io and your io.... is understood as a relative import.
To work around this, you should 'anchor' the import, like this:

import _root_.io.jvm.uuid._

which should resolve your issue.

Thanks maasg for reply. I know this feature of scala. My question was more targeted for why spark-notebook is importing something like this into user session.

I did not know about this _root_ thing however. Thanks for that.

it's due to this line:

spark-notebook/conf/scripts/init.sc

Line 4 in 1192673

import notebook._

here it's importing stuff like widgets etc.

I agree it would be better not to override the popular io package, so maybe this like can be changed, but need to be careful not break existing things...

It is not a question. It is usability issue report. Do I understand correctly that nothing will be done about this?

it can be fixed, but it's hard not to overlook something...
