flume cd

A flume task is an agent that consists of three parts, as shown in the figure: Mainly focus on source and sink. Source is divided into active source and passive source. Sink such as HDFs client, Kafka client, etc. TAR-ZXVF apache-flume-1.6.0-bin.tar.gz Configure Environment variables Vim ~/.bash_profile ...

The specific process is this:1, direct mode is directly connected to the Kafka node to obtain data.2. Direct-based approach: Periodically query Kafka to obtain the latest

In the use of flume found due to network, HDFs and other reasons, so that after the flume collected to the HDFs log some anomalies, performance as:1. Files that have not been closed: Files ending with tmp (default). Added to the HDFs file should be a GZ compressed file, the file with the end of TMP can not be used;2, there is a size of 0 files, such as GZ compressed file size of 0, we take this file alone d

Spooling Directory Source:The following 2 sets of parameters are explained:Fileheader and Fileheaderkey:Fileheader is a Boolean value that can be configured to TRUE or false to indicate whether the file name is added to the header of the event in the encapsulated event after the Flume has read the data.Fileheaderkey indicates that if there is a header in the event (when Fileheader is configured to True), the header stores the file name in the Basename

pool. Each sink has a priority, the higher the priority, the greater the value, such as 100 priority above 80 priority. If a sink fails to send an event, the sink with the highest priority will attempt to send the failed event. a1.sinkgroups = G1 a1.sinkgroups.g1.sinks = K1 K2 a1.sinkgroups.g1.processor.type = Failover A1.SINKGROUPS.G1.PROCESSOR.PRIORITY.K1 = 5 a1.sinkgroups.g1.processor.priority.k2 = ten A1.sinkgroups.g1.processor.maxpenalty = 10000 The above configuration group has K1, K2 tw

1.flume is a distributed log collection system that transmits collected data to its destination. 2.flume has a core concept, called an agent. The agent is a Java process that runs on the Log collection node. The 3.agent consists of 3 core components: source, channel, sink. The 3.1 source component is dedicated to collecting logs and can handle various types of log data in various formats, including Avro, th

Flume Monitoring Directory Operations One: Flume monitoring directory operation file Requirements:监控某个目录，若目录下面产生成符合条件的文件，flume 就抽取它到hdfs 上，目录 下可能有多中文件，比如当文件以log.tmp 结尾表示正在写，对log.tmp 文件设置size 值，就会变成一个以.log 结尾，则已经是完整文件（往往存在短暂），flume 可以抽取其中的数据，以log.completed 结尾则表示flum
