[英]Spark MLLIB questions

原文 2015-04-04 18:20:24 4 1 scala/ apache-spark/ apache-spark-mllib

I am looking into the source code of Spark-mllib, and I noticed all the source code are in scala, not java. 我正在查看Spark-mllib的源代码，我注意到所有源代码都在scala中，而不是java中。

Wouldn't scala in general use more resources than Java? scala通常不会使用比Java更多的资源吗？ Why the ML engine here is written in scala, not Java? 为什么这里的ML引擎是用Scala而不是Java编写的？ Am I missing anything here? 我在这里想念什么吗？

Also, Eclipse Luna seems to have trouble coordinate with the latest version of scala? 另外，Eclipse Luna似乎无法与最新版本的scala协调？ Which IDE would people recommend for build the spark code with scala modules? 人们建议使用哪种IDE使用Scala模块构建Spark代码？

Thank you very much! 非常感谢你！
