Hello community, name is Igor and I'm working in my spare time on a trading system. So far I used jupyter notebook with python kernel for visualisation/playing around with data. I wanted to go a step forward and reuse my existing scala code, so I came up with toree as seemingly the only one still maintained jupyter kernel.
Therefore I've assembled a jar via sbt and tried to add it in the notebook. It has failed with an exact same error as here. https://stackoverflow.com/questions/46403426/adding-dependency-to-apache-toree-fails-on-import 2018-05-18 23:43:51 WARN MagicManager:111 - Magic AddJar failed to execute with error: object Predef does not have a member classOf scala.reflect.internal.FatalError: object Predef does not have a member classOf 2018-05-18 23:43:51 ERROR OneForOneStrategy:159 - object Predef does not have a member classOf scala.reflect.internal.FatalError: object Predef does not have a member classOf So I've tried to import the jar via toree_opts like sudo jupyter toree install --spark_home=/path/bin/spark-2.3.0 --toree_opts='--jar-dir /path/target/scala-2.12' which didn't make any impact unfortunately (from source code I could see that it should print a message that jar could not be loaded, neither did an import work). I could assume that it's maybe a scala version issue? My project is compiled against 2.12.3, I couldn't find scala version that toree is using. Did somebody face this issue? How could I debug what is wrong? Thanks Best regards, Igor
