DataSetCreator관련 job돌리면 "Illegal character in fragment at index.."라는 오류가 발생하며
작업이 실해하는 경우가 있는데 이는 HDFS에 만들려는 인자에 '/'가 포함되어 있어서 문제가 발생하는 경우이다.
Helper.scala의 createDirInHDFS() 함수의 hdfs dfs -mkdir 명령에 이어서 -p옵션을 추가해주고 컴파일해서 실행한다.
그리고 URI자체에 영문과 숫자 '/', '.'만 포함하고 '<', '>', '#', '//', ':', ')', '(', ',', '&', '^'등이 들어가지 않도록 특정문자로 치환해준다.
