如何从指定的网络端口上采集日志到控制台输出和HDFS

小编给大家分享一下如何从指定的网络端口上采集日志到控制台输出和hdfs，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

需求1：
从指定的网络端口上采集日志到控制台输出和HDFS

负载算法

故障转移：可以指定优先级，数字越大越优先

a1.sinkgroups.g1.processor.type = failover

a1.sinkgroups = g1a1.sinkgroups.g1.sinks = k1 k2a1.sinkgroups.g1.processor.type = failovera1.sinkgroups.g1.processor.priority.k1 = 5a1.sinkgroups.g1.processor.priority.k2 = 10a1.sinkgroups.g1.processor.maxpenalty = 10000

全部轮询

a1.sinkgroups.g1.processor.type = load_balance

#从指定的网络端口上采集日志到控制台输出和HDFS

a1.sources = r1a1.sinks = k1 k2 a1.channels = c1# Describe/configure the sourcea1.sources.r1.type = netcata1.sources.r1.bind = 0.0.0.0a1.sources.r1.port = 44444# Describe the sinka1.sinkgroups = g1a1.sinkgroups.g1.sinks = k1 k2a1.sinkgroups.g1.processor.type = load_balancea1.sinks.k1.type = loggera1.sinks.k2.type = hdfsa1.sinks.k2.hdfs.path = hdfs://192.168.0.129:9000/user/hadoop/flumea1.sinks.k2.hdfs.batchSize = 10a1.sinks.k2.hdfs.fileType = DataStreama1.sinks.k2.hdfs.writeFORMat = Text# Use a channel which buffers events in memorya1.channels.c1.type = memorya1.channels.c1.capacity = 1000a1.channels.c1.transactionCapacity = 100# Bind the source and sink to the channela1.sources.r1.channels = c1a1.sinks.k1.channel = c1a1.sinks.k2.channel = c1

检查logger输出：

检查hdfs输出：
