#exec-memory-logger.conf內容
# a1可以看做是flume服務的名稱，每個flume都由sources、channels和sinks三部分組成
# sources可以看做是資料來源頭、channels是中間轉存的渠道、sinks是資料後面的去向
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# 配置Source
a1.sources.r1.type = exec

a1.sources.r1.shell = /bin/sh -c
#a1.sources.r1.command = for i in /path/*.txt; do cat $i; done

# 配置Channel
a1.channels.c1.type = memory

# 配置Sinks
a1.sinks.k1.type = logger

# Bind the source and sink to the channel 
#將指定source（r1）和channel（c1）繫結
#再將sink(k1)和channel（c1）繫結
#則：source（r1）和 sink(k1)已經連通
