Flume - 无法配置接收器 - 没有为接收器配置通道

Question

我已经配置了flume来读取日志文件并写入HDFS.当我启动水槽时,会读取日志文件,但不会写入HDFS.flume.log有警告信息 - could not configure sink - no channel configured for sink但我已经在conf文件中分配了一个信道.

下面给出了conf-file和错误消息:

File: spool-to-hdfs.properties
# List all components.
agent1.sources = source1
agent1.sinks = sink1
agent1.channels = channel1

# Describe source.
agent1.sources.source1.type = spooldir
agent1.sources.source1.spoolDir =/Suriya/flume/input_files

# Describe channel
#agent1.channels.channel1.type = file
#agent1.channels.channel1.checkpointDir = /Suriya/flume/checkpointDir
#agent1.channels.channel1.dataDirs =/Suriya/flume/dataDirs
agent1.channels.channel1.type = memory

# Describe sink
agent1.sinks.sink1.type = hdfs
#agent1.sinks.sink1.hdfs.path = hdfs://sandbox.hortonworks.com:8020/hdfs/Suriya/flume
agent1.sinks.sink1.hdfs.path = hdfs://localhost/hdfs/Suriya/flume
agent1.sinks.sink1.hdfs.fileType= DataStream
agent1.sinks.sink1.hdfs.writeFormat = Text

# Bind source and sink to channel
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channels = channel1

**-- starting the agent**
flume-ng agent --conf-file spool-to-hdfs.properties --conf /etc/flume/conf --name agent1;

flume.log

Replace the bind part with.

# Bind source and sink to channel
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channels = channel1

This bind config
# Bind source and sink to channel
agent1.sources.source1.channels = channel1
agent1.sinks.sink1.channel = channel1


agent1.sources.source1.channels = channel1 
Looks okay

BUT
agent1.sinks.sink1.channels = channel1
Should be 
agent1.sinks.sink1.channel = channel1

让我们知道怎么回事.
