如何使用spark-shell導入自己的scala包？

Question

我已經寫了spark-ml庫的一個類，它使用了另一個類。 如果要清楚，我的類是RandomForestClassifier的包裝。 現在我想有機會從spark-shell導入這個類。

所以問題是：如何製作包含我自己的類的包，它將能夠從spark-shell導入？非常感謝！

Answer 1

閱讀文檔：

In the Spark shell, a special interpreter-aware SparkContext is already created for you, in the variable called sc. Making your own SparkContext will not work. You can set which master the context connects to using the --master argument, and you can add JARs to the classpath by passing a comma-separated list to the --jars argument. You can also add dependencies (e.g. Spark Packages) to your shell session by supplying a comma-separated list of maven coordinates to the --packages argument. Any additional repositories where dependencies might exist (e.g. SonaType) can be passed to the --repositories argument.

如果要導入未編譯的文件，如Hello.scala，火花殼做如下：

scala> :load ./src/main/scala/Hello.scala
