| //! HDFS as a remote ObjectStore for [Datafusion](https://github.com/apache/datafusion). |
| //! |
| //! This crate introduces ``HadoopFileSystem`` as a remote ObjectStore which provides the ability of querying on HDFS files. |
| //! |
| //! For the HDFS access, We leverage the library [fs-hdfs](https://github.com/datafusion-contrib/fs-hdfs). |
| //! Basically, the library only provides Rust FFI APIs for the ``libhdfs`` which can be compiled by a set of C files provided by the [official Hadoop Community](https://github.com/apache/hadoop). |
