sortByKey trouble
Hi,
Does anybody know how to use sortbykey in scala on a RDD like :
val rddToSave = file.map(l => l.split("\\|")).map(r => (r(34)+"-"+r(3),
r(4), r(10), r(12)))
besauce, i received ann error "sortByKey is not a member of
ord.apache.spark.rdd.RDD[(String,String,String,String)].
What i try do do is sort on the first element.
Thank's

Thanks.

i've already try this solution but it does not compile (in Eclipse)
I'm surprise to see that in Spark-shell, sortByKey works fine on 2
solutions :
(String,String,String,String)
(String,(String,String,String))

Hi David,
Can you try val rddToSave = file.map(l => l.split("\\|")).map(r =>
(r(34)+"-"+r(3), (r(4), r(10), r(12)))) ?
That should work.

Hi,
SortByKey is only for RDD[(K, V)], each tuple can only has two members, Spark will sort with first member, if you want to use sortByKey, you have to change your RDD[(String, String, String, String)] into RDD[(String, (String, String, String))].
Thanks
