Hi,

what does the code do RDD.map(e => e.split(",")(1)) in spark with scala?

I know RDD.map(e => e.split(",")) would split a string with ',' separated. But, I don't get the (1) in the code. Could somebody give me some information on this? I would greatly appreciate your answer. Thanks!

I'm not familiar with Scala but their docs are similar to Java so I would guess it would return the item at the first index of the result array.
