Read-only disc memory CD-ROM is the normal CD that we often use. CD-ROM discs can be used to cross storage of large volumes of text, sound, graphics and images and other media digital information for quick retrieval, so the CD-ROM drive has become a standard configuration of multimedia computers.

ObjectiveFirst look at the definition of event in Flume official websiteA line of text content is deserialized into an event "serialization is the process of converting an object's state into a format that can be persisted or transmitted. Relative to serialization is deserialization, which transforms a stream into an object. These two processes combine to make it easy to store and transfer data ", the maximum definition of event is 2048 bytes, exceedi

From Bin/flume this shell script can see Flume starting from the Org.apache.flume.node.Application class, which is where the main function of Flume is.The Main method first parses the shell command, assuming that the specified configuration file does not exist and then dumps the exception.According to the command contains the "no-reload-conf" parameters, decided

Kafkasink.jar, copy it to the Flume/lib directory on the node where Flume resides, and then you need to Kafka_2.10-0.8.2.0.jar, Kafka-clients-0.8.2.0.jar, Metrics-core-2.2.0.jar, Scala-library-2.10.4.jar These 4 jar packages are copied to the Flume/lib directory on the node where Flume resides.3.

IconAs shown in the Red box section, I do stability testing, when the flume run a few days later, I found that the counter value gradually become larger, to a certain value, and then become smaller, there is a cycle of the process, and therefore the desire to produce research, the following to see:if (Txneventcount = = 0) { sinkcounter.incrementbatchemptycount (); } else if (Txneventcount = = batchsize) { Sinkcounter.incrementbatchc

Multiplexing technology is intended to send an event to a specific channel based on configuration information.A source instance can specify multiple channels, but a sink instance can only specify one channel.Flume supports fanning out the flow from one source to multiple channels. There is modes of fan out, replicating and multiplexingFlume supports two modes of output from source to multiple channel: copy and Reuse1. In copy mode, the event data received by source is output to all channel confi

I. Introduction of FlumeFlume is a distributed, reliable, and highly available mass-log aggregation system that enables the customization of various data senders in the system for data collection, while Flume provides the ability to simply process the data and write to various data-receiving parties (customizable).Design objectives:(1) ReliabilityWhen a node fails, the log can be transmitted to other nodes without loss.

good performance where multiple disks is not available for checkpoint and data Directori Es.It is natural that the channel data is synchronized to disk and performance degrades, but the checkpoint mechanism is added to prevent data loss.For the deformed memory channel, which is the memory channel and the file channel used together, we do not explain here, because this mixed use, the official also give hints-not recommended in the production environment to use.The reason for this is that data lo

2017-09-06 Zhu Big Data and cloud computing technologies Any production system will produce a large number of logs during operation, and the log often hides a lot of valuable information. These logs are stored for a period of time and are cleaned up before the method is parsed. With the development of technology and the improvement of analytical ability, the value of log is re-valued. Before you analyze these logs, you need to collect the logs that are scattered across production systems. Thi
