Luciano Resende commented on TOREE-495:
---------------------------------------

[~standa] I thought I was following your use case, untill the moment you 
mentioned that the --deps-dir would be defined during the installation. To me, 
%addJar and %addDeps are to add dependencies required to a specific notebook 
and are transient in the sense that are not always required to everybody, or 
different users might have different versions, and so on... If you sort of know 
where these are, and these are always on the same location, why not add the 
path to Python classpath in the kernelspec? 

Please feel free to give more details on what issue you are trying to solve by 
adding the --deps-dir outside from the magic parameters itself. Also, please 
consider how would this work in a distributed environment (e.g. YARN cluster 
mode).

> It would be helpful to have option, where are dependencies stored with 
> AddDeps magic. Currently there is only {{jar-dir option for AddJar magic.}}
> {{We create new deps-dir attribute for toree_opts. This option can be then 
> used in install command:}}
> {code:java}
> jupyter toree install --toree_opts="--deps-dir=/path/to/deps"{code}
