我是hadoop新手，我正在使用cloudera quickstart，我想将flume与我的mongodb连接起来。我不知道如何连接flume到mongodb，mongodb设置了用户名和密码。我使用源类型作为 netcat ，通道类型为 memory Flume类型为 hdfs .
我的 flume.conf 文件

# Please paste flume.conf here. Example:

# Sources, channels, and sinks are defined per

# agent name, in this case 'tier1'.

tier1.sources  = source1
tier1.channels = channel1
tier1.sinks    = sink1

# For each source, channel, and sink, set

# standard properties.

tier1.sources.source1.type     = netcat
tier1.sources.source1.bind     = 192.168.x.xxx
tier1.sources.source1.port     = 27017
tier1.sources.source1.channels = channel1
tier1.channels.channel1.type   = memory
tier1.sinks.sink1.type         = hdfs
tier1.sinks.sink1.hdfs.path    = /user/cloudera/flume
tier1.sinks.sink1.hdfs.fileType = DataStream
tier1.sinks.sink1.channel      = channel1

# Other properties are specific to each type of

# source, channel, or sink. In this case, we

# specify the capacity of the memory channel.

tier1.channels.channel1.capac
