How to transfer data from one system to another system's HDFS (connected through LAN) using Flume?

I have a computer in LAN Connection . I need to transfer data from the system to another system's HDFS location using flume.

I have tried using ip address of the sink system, but it didn't work. Please help..

Regards,

This can be achieved by using avro mechanism.

The flume has to be installed in both the machines. A config file with the following codes has to be made to be run in the source system , where the logs are generated.

a1.sources = tail-file
a1.channels = c1
a1.sinks=avro-sink

a1.sources.tail-file.channels = c1
a1.sinks.avro-sink.channel = c1
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000

a1.sources.tail-file.type = spooldir
a1.sources.tail-file.spoolDir =<location of spool directory>
a1.sources.tail-file.channels = c1
a1.sinks.avro-sink.type = avro
a1.sinks.avro-sink.hostname = <IP Address of destination system where the data has to    be written>   
a1.sinks.avro-sink.port = 11111

A config file with the following codes has to be made to be run in the destination system , where the logs are generated.

a2.sources = avro-collection-source
a2.sinks = hdfs-sink
a2.channels = mem-channel

a2.sources.avro-collection-source.channels = mem-channel
a2.sinks.hdfs-sink.channel = mem-channel
a2.channels.mem-channel.type = memory
a2.channels.mem-channel.capacity = 1000

a2.sources.avro-collection-source.type = avro
a2.sources.avro-collection-source.bind = localhost
a2.sources.avro-collection-source.port = 44444

a2.sinks.hdfs-sink.type = hdfs
a2.sinks.hdfs-sink.hdfs.writeFormat = Text
a2.sinks.hdfs-sink.hdfs.filePrefix =  testing
a2.sinks.hdfs-sink.hdfs.path = hdfs://localhost:54310/user/hduser/

Now, the data from the log file in the source system will be written to hdfs system in the destination system.
