我是新来的ApacheFlume。
我试图了解如何获取json（作为http源代码），解析它并根据内容将其存储到hdfs上的动态路径。
例如：
如果json是：

[{   
  "field1" : "value1",
  "field2" : "value2"
}]

那么hdfs路径将是：
/某个默认根路径/value1/value2/某个值名称文件
有没有这样的Flume配置，使我能够做到这一点？
以下是我当前的配置（通过http接受json，并根据时间戳将其存储在路径中）：

# flume.conf: http source, hdfs sink

# Name the components on this agent

a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source

a1.sources.r1.type =  org.apache.flume.source.http.HTTPSource
a1.sources.r1.port = 9000

# a1.sources.r1.handler = org.apache.flume.http.JSONHandler

# Describe the sink

a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = /user/uri/events/%y-%m-%d/%H%M/%S
a1.sinks.k1.hdfs.filePrefix = events-
a1.sinks.k1.hdfs.round = true
a1.sinks.k1.hdfs.roundValue = 10
a1.sinks.k1.hdfs.roundUnit = minute

# Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel

a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

谢谢！
