new feature: Use hdfs jni directly instead of using libhdfs

[Xuanwo]

Feature Description

libhdfs needs to call Java via Rust -> C -> Java, which introduces additional overhead. It might be more efficient to call JNI directly, bypassing the dependency on libhdfs.

Problem and Solution

Implement hdfs via jni directly without libhdfs.

Additional Context

It primarily seems like rewriting libhdfs in Rust.
