Now,I have a map val ji = scala.collection.mutable.Map[String,scala.collection.mutable.ArrayBuffer[String]]() there are so many datas like: ji = map("a"->ArrayBuffer["1","2","3"],"b"->ArrayBuffer["1","2","3"],"c"->ArrayBuffer["2","3"])
if "a" choose "1","b" and "c" can't choose "1", for example, ji = map("b"->ArrayBuffer["2","3"],"c"->ArrayBuffer["2","3"]) if "b" choose "2","c" can't choose "2", for example, ji = map("c"->ArrayBuffer["3"]) And I need get all the Possibilities and sort them from small to big and ouput them to result.txt. Results Like: a:1 b:2 c:3 a:1 c:2 b:3 b:1 a:2 c:3 b:1 c:2 a:3 Finally,we can get result.txt: a b c a c b b a c b c a What should I do? I think it is difficult to me..... -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/deal-with-datas-structure-tp26349.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
