我正面临一个奇怪的问题。我正在寻找从flume到hdfs的大量信息。我应用了推荐的配置来避免太多的小文件，但它不起作用。这是我的配置文件。

# single-node Flume configuration

# Name the components on this agent

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

# Describe/configure the source

a1.sources.r1.type = avro
a1.sources.r1.bind = 0.0.0.0
a1.sources.r1.port = 5458
a1.sources.r1.threads = 20

# Describe the HDFS sink

a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = hdfs://myhost:myport/user/myuser/flume/events/%{senderType}/%{senderName}/%{senderEnv}/%y-%m-%d/%H%M
a1.sinks.k1.hdfs.filePrefix = logs-
a1.sinks.k1.hdfs.fileSuffix = .jsonlog
a1.sinks.k1.hdfs.fileType = DataStream
a1.sinks.k1.hdfs.writeFormat = Text
a1.sinks.k1.hdfs.batchSize = 100
a1.sinks.k1.hdfs.useLocalTimeStamp = true

# never roll-based on time

a1.sinks.k1.hdfs.rollInterval=0

## 10MB=10485760, 128MB=134217728, 256MB=268435456

a1.sinks.kl.hdfs.rollSize=10485760

## never roll base on number of events

a1.sinks.kl.hdfs.rollCount=0
a1.sinks.kl.hdfs.round=false

# Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 5000
a1.channels.c1.transactionCapacity = 1000

# Bind the source and sink to the channel

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

这个配置工作，我看到我的文件。但是文件的平均重量是1.5kb。flume控制台输出提供这种信息。

有人对这个问题有想法吗？
下面是一些关于Flume行为的信息。
命令是flume ng agent-n a1-c/path/to/flume/conf--conf文件sample-flume.conf-dflume.root.logger=trace，console-xms8192m-xmx16384m
注意：logger指令不起作用。我不明白为什么但是我。。。
Flume启动输出为：

因为我不能有更详细的输出，我不得不假设

[...]

16/08/03 15:32:55 INFO conf.FlumeConfiguration: Processing:k1
[...]

指示接收器配置正确。
附言：我看到了以下答案，但没有一个作品（我应该错过一些…）。
flume hdfs sink在hdfs上生成许多小文件
小文件太多hdfsFlume
flume使用avro源和汇分层数据流
FlumehdfsFlume不断滚动小文件
