Subject Error in Upload the log file into hdfs
Date Thu, 29 Nov 2012 12:03:11 GMT
Hi,

I am just struggling to learn the flume and doing some testing. I am
running two agents (agent, agent1). The agent used to upload the log data
into hdfs and agent1 used as logger. The configuration of two agents as:

agent.sources = tail
agent.channels = memoryChannel
agent.sinks = hdfs-clusterSink

agent.sources.tail.type = exec
agent.sources.tail.command = tail -f /var/log/flume-ng/flume.log
agent.sources.tail.channels = memoryChannel

agent.sinks.hdfs-clusterSink.
channel = memoryChannel
agent.sinks.hdfs-clusterSink.type = hdfs
agent.sinks.hdfs-clusterSink.hdfs.path = hdfs://
hadoop1.example.com/user/root/Test/


agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.transactionCapacity=1000
agent.channels.memoryChannel.capacity = 100




agent1.sources = source1
agent1.sinks = sink1
agent1.channels = channel1

# Describe/configure source1
agent1.sources.source1.type = netcat
agent1.sources.source1.bind = localhost
agent1.sources.source1.port = 44444

# Describe sink1
agent1.sinks.sink1.type = logger

# Use a channel which buffers events in memory
agent1.channels.channel1.type = memory
agent1.channels.channel1.capacity = 1000
agent1.channels.channel1.transactionCapactiy = 100

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


I dont know why it does not upload the log file into hdfs. where I am doing
mistake . If anyone who have solution please let me know.


The log file as:
