I have my custom Source and Sink that I have hooked with a memory channel but I am noticing that it is not very consistent. Even after sending many events to the Source the Sink’s event is still null. It works for about 1 out 4 events. I do see the events going to the Logger Sink so I know the Source is doing its job. However, for the custom Sink I simply get Event is null messages. I tried adjusting the channel capacity from 10 to 1 but no difference.
Thanks. Here’s my conf file # flume-httpxmlhttp.conf: A single-node Flume with Http Source and Http sink configuration # Name the components on this agent agent1.sources = r1 agent1.channels = c1 # Describe/configure the source agent1.sources.r1.type = org.apache.flume.source.http.HTTPSource agent1.sources.r1.port = 5140 agent1.sources.r1.handler = main.java.org.apache.flume.source.http.XMLHandler agent1.sources.r1.handler.nickname = random props # Setup the sinks agent1.sinks = httpsink logsink # Describe the sink agent1.sinks.logsink.type = logger # Describe the sink agent1.sinks.httpsink.type = main.java.org.apache.flume.sink.http.HttpPostSink agent1.sinks.httpsink.serverAddress = <my http server URL> # Use a channel which buffers events in memory agent1.channels.c1.type = memory agent1.channels.c1.capacity = 1 agent1.channels.c1.transactionCapacity = 1 # Bind the source and sink to the channel agent1.sources.r1.channels = c1 agent1.sinks.logsink.channel = c1 agent1.sinks.httpsink.channel = c1
