我有3个节点的集群，使用5.9版本的最新cloudera包。操作系统是centos 6.7的所有三个。我是第一次用Flume。
我的目的是将网页数据流到hdfs中。然而，这个网页是一个第三方网站，新闻网站在我的情况下，所以我不知道该使用哪个端口连接。
curl和telnet发生在端口80上，因此我使用了它。但是有个错误。
我的flume.conf是：

tier1.sources  = http-source
tier1.channels = mem-channel-1
tier1.sinks    = hdfs-sink
tier1.sources.http-source.type     = http
tier1.sources.http-source.handler = org.apache.flume.source.http.JSONHandler
tier1.sources.http-source.bind     = 132.247.1.32
tier1.sources.http-source.port     = 80
tier1.sources.http-source.channels = mem-channel-1
tier1.channels.mem-channel-1.type   = memory
tier1.sinks.hdfs-sink.type         = hdfs
tier1.sinks.hdfs-sink.channel      = mem-channel-1
tier1.sinks.hdfs-sink.hdfs.path    = /flume/events/%y-%m-%d/%H%M/%S

# 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.mem-channel-1.capacity = 100

错误
