Hello, I'm a newbie with Spark but I've been working with Hadoop for a while. I have two questions.
Is there any case where MR is better than Spark? I don't know what cases I should be used Spark by MR. When is MR faster than Spark? The other question is, I know Java, is it worth it to learn Scala for programming to Spark or it's okay just with Java? I have done a little piece of code with Java because I feel more confident with it,, but I seems that I'm missed something --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
