Spark实践之Spark Streaming

首先需要安装flume，我选择的是1.9.0版本，然后对于配置文件只需要配置相关的环境和jdk即可

flume-env.sh

export JAVA_HOME=/usr/local/java8/jdk1.8.0_371

# Give Flume more memory and pre-allocate, enable remote monitoring via JMX
# export JAVA_OPTS="-Xms100m -Xmx2000m -Dcom.sun.management.jmxremote"

# Let Flume write raw event data and configuration information to its log files for debugging
# purposes. Enabling these flags is not recommended in production,
# as it may result in logging sensitive user information or encryption secrets.
# export JAVA_OPTS="$JAVA_OPTS -Dorg.apache.flume.log.rawdata=true -Dorg.apache.flume.log.printconfig=true "

# Note that the Flume conf directory is always included in the classpath.
#FLUME_CLASSPATH=""

使用 Avro 数据源测试 Flume

先创建文件helloword.txt和avro.conf

helloword.txt

Hello World
Hello Flume

avro.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.channels = c1
a1.sources.r1.bind = 0.0.0.0
a1.sources.r1.port = 4141

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

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

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

 

flume-ng agent -c /usr/local/flume-1.9.0/conf -f  /usr/local/flume-1.9.0/conf/avro.conf -n a1 Dflume.root.logger=INFO,console

 

/usr/local/flume-1.9.0/bin/flume-ng avro-client -H localhost -p 4141 -F /home/bill/test/helloworld.txt

 

 

使用 netcat 数据源测试 Flume

创建netcat.conf

 

# netcat.conf: A single-node Flume configuration

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

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

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

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

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

 

yum list telnet*          # 列出telnet相关的安装包
yum install telnet-server  # 安装telnet服务
yum install telnet.*      # 安装telnet客户端

 

flume-ng agent -c /usr/local/flume-1.9.0/conf -f  /usr/local/flume-1.9.0/conf/netcat.conf -n a1 -Dflume.root.logger=INFO,console

 

 telnet localhost 44444
