Hi,
What is the throughput I can expect when writing to the HDFS Sink. Here is the
flume config I'm using:
# in this case called 'agent'
# Define a memory channel called ch1 on agent1
agent1.channels.ch1.type = memory
# Define an exec source called exec-source1 on agent1 and tell it
# to bind to 0.0.0.0:41414. Connect it to channel ch1.
agent1.sources.exec-source1.channels = ch1
agent1.sources.exec-source1.type = exec
agent1.sources.exec-source1.restart = true
agent1.sources.exec-source1.batchSize = 100
agent1.sources.exec-source1.command = /home/ubuntu/flume/linesource.sh
# Define a logger sink that simply logs all events it receives
# and connect it to the other end of the same channel.
agent1.sinks.hdfs-sink1.channel = ch1
agent1.sinks.hdfs-sink1.type = hdfs
agent1.sinks.hdfs-sink1.hdfs.path =
hdfs://ip-10-000-000-000.ec2.internal/user/ubuntu/event
agent1.sinks.hdfs-sink1.hdfs.filePrefix = event
agent1.sinks.hdfs-sink1.hdfs.writeFormat = Text
agent1.sinks.hdfs-sink1.hdfs.rollInterval = 60
agent1.sinks.hdfs-sink1.hdfs.rollCount = 0
agent1.sinks.hdfs-sink1.hdfs.rollSize = 0
agent1.sinks.hdfs-sink1.hdfs.fileType = DataStream
agent1.sinks.hdfs-sink1.hdfs.batchSize = 1000
# Finally, now that we've defined all of our components, tell
# agent1 which ones we want to activate.
agent1.channels = ch1
agent1.sources = exec-source1
agent1.sinks = hdfs-sink1
So far I only get about 20Mb/min or less than 1 Mb/sec. I am wondering how far
it can be improved. Is there any Benchmark on HDFS Sink performance.
Thanks in Advance,
Pankaj
