Я только что установил искру на свою новую машину и получил следующую ошибку после установки Java, Scala и Apache-искры с использованием homebrew. Процесс установки приведен ниже:
$ brew cask install java
$ brew install scala
$ brew install apache-spark
После установки, когда я пытаюсь запустить базовый пример с помощью spark-shell
, я получаю следующую ошибку. Любая помощь была высоко оценена.
$ spark-shell
Using Spark default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
Failed to initialize compiler: object java.lang.Object in compiler mirror not found.
** Note that as of 2.8 scala does not assume use of the java classpath.
** For the old behavior pass -usejavacp to scala, or if using a Settings
** object programmatically, settings.usejavacp.value = true.
