Hello, everyone.

I'm the maintainer of [hdfs-sys]: A binding to HDFS Native C API for Rust. I 
want to know is it a good idea of accepting hdfs-sys as a part of hadoop 
project?

Users of hdfs-sys for now:

- [OpenDAL]: An Apache Incubator project that allows users to easily and 
efficiently retrieve data from various storage services in a unified way.
- [Databend]: A modern cloud data warehouse focusing on reducing cost and 
complexity for your massive-scale analytics needs. (via OpenDAL)
- [RisingWave]: The distributed streaming database: SQL stream processing with 
Postgres-like experience. (via OpenDAL)
- [LakeSoul]: an end-to-end, realtime and cloud native Lakehouse framework

Licenses information of hdfs-sys:

- hdfs-sys itself licensed under Apache-2.0
- hdfs-sys only depends on the following libs: cc@1.0.73, glob@0.3.1, 
hdfs-sys@0.3.0, java-locator@0.1.5, lazy_static@1.4.0, they are all dual 
licensed under Apache-2.0 and MIT.

Works need to do if accept:

- Replace libdirent with the same dirent API implemented in HDFS project.
- Remove all bundled hdfs C code.
