What is Apache Flume?
Apache Flume is an open-source, powerful, reliable and flexible system used to collect, aggregate and move large amounts of unstructured data from multiple data sources into HDFS/Hbase (for example) in a distributed fashion via it’s strong coupling with the Hadoop cluster.
Why do we use Apache Flume?
Apache Flume is a distributed, reliable, and available system for efficiently collecting, aggregating and moving large amounts of log data from many different sources to a centralized data store. The use of Apache Flume is not only restricted to log data aggregation.
What is Apache Flume describe the features components and working of Apache Flume?
Apache Flume – Introduction Apache Flume is a tool/service/data ingestion mechanism for collecting aggregating and transporting large amounts of streaming data such as log files, events (etc…) from various sources to a centralized data store. Flume is a highly reliable, distributed, and configurable tool.
What are the features of Flume?
Features of Apache Flume

Where is Apache Flume used?
Apache Flume is a reliable and distributed system for collecting, aggregating and moving massive quantities of log data. It has a simple yet flexible architecture based on streaming data flows. Apache Flume is used to collect log data present in log files from web servers and aggregating it into HDFS for analysis.

How does Apache Flume work?
Apache Flume can store data in centralized stores (i.e data is supplied from a single store) like HBase & HDFS. Flume is horizontally scalable. If the read rate exceeds the write rate, Flume provides a steady flow of data between read and write operations. Flume provides reliable message delivery.
What are the activities that Flume can perform?
Answer: A distributed service for collecting, aggregating, and moving large amounts of log data, is Flume.
What is difference between Flume and sqoop?
1. Sqoop is designed to exchange mass information between Hadoop and Relational Database. Whereas, Flume is used to collect data from different sources which are generating data regarding a particular use case and then transferring this large amount of data from distributed resources to a single centralized repository.
Where is Flume used?
Apache Flume is used to collect log data present in log files from web servers and aggregating it into HDFS for analysis. Apache log4j (enable Java applications to write events to files in HDFS via Flume).
Which is important for multifunction Flume agents?
In Multi agent flows, the sink of the previous agent (ex: Machine1) and source of the current hop (ex: Machine2) need to be avro type with the sink pointing to the hostname or IP address and port of the source machine. So, thus Avro RPC mechanism acts as the bridge between agents in multi hop flow.
Is Flume a ETL tool?
Apache Sqoop and Apache Flume are two popular open source etl tools for hadoop that help organizations overcome the challenges encountered in data ingestion.
Which is an example of an Apache Flume system?
Apache Flume is a system used for moving massive quantities of streaming data into HDFS. Collecting log data present in log files from web servers and aggregating it in HDFS for analysis, is one common example use case of Flume. Flume supports multiple sources like –
When to use Apache Flume for Hadoop analysis?
Assume an e-commerce web application wants to analyze the customer behavior from a particular region. To do so, they would need to move the available log data in to Hadoop for analysis. Here, Apache Flume comes to our rescue. Flume is used to move the log data generated by application servers into HDFS at a higher speed.
How to transfer one file at a time in Apache Flume?
Using put command, we can transfer only one file at a time while the data generators generate data at a much higher rate. Since the analysis made on older data is less accurate, we need to have a solution to transfer data in real time. If we use put command, the data is needed to be packaged and should be ready for the upload.
When did Apache Flume 1.9.0 come out?
January 8, 2019 – Apache Flume 1.9.0 Released The Apache Flume team is pleased to announce the release of Flume 1.9.0. Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of streaming event data. Version 1.9.0 is the eleventh Flume release as an Apache top-level project.
