구성요소
****Source 다양한 원천 시스템의 데이터 수집위해  Avro, Thrift, JMS, Spool Dir , Kafka, 등 여러 컴포넌트 제공, 수집한 데이터 Channel로 전달
****Sink 수집한 데이터를 Channel로 부터 전달받아 최종 목적지에 저장하기 위한 기능으로 HDFS, Hive, Logger, Avro, ElasticSearch Thrift등을 제공. 
***Channel Source와 Sink를 연결 데이터를 버퍼링하는 컴포넌트로 메모리,파일, 데이터베이스 채널 의 저장소로 활용. 
Interceptor Source와 Channel사이에 데이터 필터링 및 가공하는 컴포넌트로서 Timestamp, Host, Regex, Filttering 등을 기본 제공하며, 필요 시 사용자 정의 Interceptor 추가.
