flume load balancing load balancer

Load balancing is used to solve a machine (a process) can not solve all requests an algorithm generated. Load balancing Sink Processor load balance function can be realized, as shown Agent1 is a routing node, it is responsible for the temporarily stored Channel Event Sink equalized to a plurality of corresponding components, and each component is connected to a Sink separate - Agent, example configuration as follows:

Here we load balanced analog flume through three machines

Three machines planned as follows:

node01: collecting data, transmitted to the machine up node02 and node03

node02: a data receiving portion of node01

node03: a data receiving portion of node01

The first step : developing node01 server 's flume configuration

node01 server configuration:

cd /export/servers/apache-flume-1.6.0-cdh5.14.0-bin/conf

vim load_banlancer_client.conf

#agent name
a1.channels = c1
a1.sources = r1
a1.sinks = k1 k2

#set gruop
a1.sinkgroups = g1
#set sink group
a1.sinkgroups.g1.sinks = k1 k2

#set sources
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /export/taillogs/access_log

#set channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# set sink1
a1.sinks.k1.type = avro
a1.sinks.k1.hostname = node02
a1.sinks.k1.port = 52021

# set sink2
a1.sinks.k2.type = avro
a1.sinks.k2.hostname = node03
a1.sinks.k2.port = 52021


#set failover
a1.sinkgroups.g1.processor.type = load_balance
a1.sinkgroups.g1.processor.backoff = true
a1.sinkgroups.g1.processor.selector = round_robin
a1.sinkgroups.g1.processor.selector.maxTimeOut=10000


a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
a1.sinks.k2.channel = c1

Step two : development node02 server 's configuration flume

cd /export/servers/apache-flume-1.6.0-cdh5.14.0-bin/conf

vim load_banlancer_server.conf

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = avro
a1.sources.r1.bind = node02
a1.sources.r1.port = 52021

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Describe the sink
a1.sinks.k1.type = logger

# Bind the source and sink to the channel 
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

The third step : the development node03 server flume configuration

node03 Server Configuration

cd /export/servers/apache-flume-1.6.0-cdh5.14.0-bin/conf

vim load_banlancer_server.conf

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = avro
a1.sources.r1.bind = node03
a1.sources.r1.port = 52021

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Describe the sink
a1.sinks.k1.type = logger

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
