Implement a Flume Deserializer Plugin to Import XML Files

Background

Flume is an open-source Apache project, it is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. This article shows how to import XML Files with Flume, including the development of a deserializer plugin and the corresponding configurations of Flume. We are using Flume 1.5.0 integrated in MapR.

The secenario is that XML files are sychronized to a directory periodically, we need to config a Spooling Directory Source to load these XML files into Flume.

Implement a Flume Deserializer

The default deserializer of Flumeā€™s Spooling Directory Source is LineDeserializer, which simply parses each line as an Flume event. In our case, we need to implement a deserializer for XML files based on the structure.
