当我想阅读文件时,我的文件格式为: 12334 this:23,word:21,teacher:23

   val fp = "/user/user_id.txt"
   sc.textFile(fp).map { s =>
   val Array(did, info_s) = s.split("\t")
   val info = info_s.split(",").map { kv =>
      val Array(k, v) = kv.split(":")
      (k, v.toDouble)
    }.toSeq
    (did, info)
  }

这个scala错误出现了.这个怎么样？
