Apache Toree и Spark Scala не работают в Jupyter

Question

У меня проблемы с Scala Spark на Jupyter. Ниже приведено мое сообщение об ошибке при загрузке ноутбука Apache Toree - Scala в jupyter.

Эта проблема была выделены ранее в JIRA https://issues.apache.org/jira/browse/TOREE-336. Тем не менее, я по-прежнему не могу заставить его работать по какой-то причине.

Я следил за инструкциями, перечисленными на их официальном сайте. https://toree.apache.org/documentation/user/quick-start

Это мой путь

scala> root@ubuntu-2gb-sgp1-01:~# echo $PATH 
/root/bin:/root/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/spark:/usr/local/spark/bin 

Пожалуйста, обратите внимание, я не установить Scala, как это происходит с искрой.

Благодаря

Мы не использовали Спарк 2.0 производства еще с Scala 2.11 и ноутбуков. Основной причиной является то, что ваша ошибка совместима. Основываясь на описании GitHub Toree, последняя версия Scala, которая поддерживается, - Scala 2.10.4, и у вас есть 2.11.8. Постарайтесь понизить его до 2.10, если это не производство, нужно использовать только 2.11
