Hadoop formats #

Apache Flink allows users to access many different systems as data sources or sinks. The system is designed for very easy extensibility. Similar to Apache Hadoop, Flink has the concept of so called InputFormats and OutputFormats.

One implementation of these InputFormats is the HadoopInputFormat. This is a wrapper that allows users to use all existing Hadoop input formats with Flink.

This section shows some examples for connecting Flink to other systems. Read more about Hadoop compatibility in Flink.
