一般来讲,你最好用idea IDE倒入这个工程,设定为maven project,然后直接执行example function里面的主函数就可以了
from sparkctr.
我下载了IntelliJ IDEA IDE, 并且import了这个project,设为maven project. 然后想run ModelSelection.scala 这个file,遇到一下error msg. 文件23行是spark读取“orc”的data resource,请问这边是读取没有权限吗?
Exception in thread "main" java.lang.NullPointerException
at com.ggstar.example.ModelSelection$.main(ModelSelection.scala:23)
at com.ggstar.example.ModelSelection.main(ModelSelection.scala)
val resourcesPath = this.getClass.getResource("/samples.snappy.orc")
val rawSamples = spark.read.format("orc").option("compression", "snappy").load(resourcesPath.getPath)
from sparkctr.
原始的数据文件目前不提供了,抱歉
