What is Flume? 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. It is principally designed to copy streaming data (log data) from various web servers to HDFS. Applications of Flume 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. Advantages of Flume Here are the advantages of using Flume − Using Apache Flume we can store the data in to any of the centralized stores (HBase, HDFS). When the rate of incoming data exceeds the rate at which data can be written to the destination, Flume acts as ...
