I'm new at using Flume and Hadoop so I'm trying to setup the simplest (but somewhat helpful/realistic) example I can. I'm using the HortonWorks Sandbox in a VM client. After following one tutorial 12 (which involves setting up and using Flume) everything seems to be working correctly.
So I setup my own flume.conf that should
Simple enough right? Here's my conf file
agent.sources=exec-source
agent.sinks=hdfs-sink
agent.channels=ch1
agent.sources.exec-source.type=exec
agent.sources.exec-source.command=tail -F /var/log/httpd/access_log
agent.sinks.hdfs-sink.type=hdfs
agent.sinks.hdfs-sink.hdfs.path=/flume/events
agent.sinks.hdfs-sink.hdfs.filePrefix=apacheaccess
agent.sinks.hdfs-sink.hdfs.rollInterval=10
agent.sinks.hdfs-sink.hdfs.rollSize=0
agent.channels.ch1.type=memory
agent.channels.ch1.capacity=1000
agent.sources.exec-source.channels=ch1
agent.sinks.hdfs-sink.channel=ch1
I've seen several people have problems writing to HDFS, and in most cases it was that there weren't enough logs to fill the HDFS block. However, rollInterval=10 should generate a new file every 10 seconds, as long as at least 1 line is written to it. I can run "tail -F /var/log/httpd/access_log" in another window and see lines being written to the log fairly consistantly, so I don't think it's that.
and here's the command/output from trying to start this agent
[root@sandbox ~]# flume-ng agent -f /etc/flume/conf/flume.conf -n apache-agent

Now at this point I realize I'm missing several things.
1) I expect to see something along the lines of "INFO instrumentation.MonitoredCounterGroup: Component type: SINK, name: hdfs-sink started" as my last line, which I don't
2) If I use the command “hadoop fs -lsr /flume” I should see new logs in my HDFS, but I don't. The last logs are from 8/28/2013, when I did the tutorial.
I also don't expect to see that WARN line in there, but I'm not sure why it's there, so maybe that's my problem and someone can tell me why.
So my questions are:
1) Can anyone tell me what might be going wrong here?
2) When I get this problem sorted out, is there anything else I should be looking for to see what Flume is working correctly, reading what it should and writing to where it should and when?
The answer is, of course, to name your agent when you start flume the same as your agent name in the config file. So my command line should have ended "-n agent" and NOT "-n apache-agent" since my flume.conf file specifies "agent.X"
After that everything appears to work.
