## What it is
A native Go client for HDFS that connects directly to the namenode via its protocol buffers API, mimicking the stdlib os package interfaces. It also ships a fast commandline client offering POSIX-like verbs (ls, rm, get, put) as a JVM-free alternative to `hadoop fs`.

## Use cases
- read and write files on HDFS from a Go program
- list, copy, and delete files on a Hadoop cluster from the shell
- replace slow `hadoop fs` commands with a fast native binary
- script HDFS operations without a JVM installed
- programmatically inspect HDFS file metadata like os.FileInfo

## When to choose
- you need HDFS access from Go without shelling out to hadoop or the JVM
- you want fast, scriptable HDFS shell commands with bash completion
- you prefer idiomatic Go APIs mirroring the os package

## When to avoid
- your cluster requires Kerberos or advanced Hadoop features not supported by the client
- you need a JVM-based Hadoop ecosystem toolchain (Hive, Spark integration)
- the project lacks an active maintainer and you need guaranteed long-term support

## Facets
- artifact type: library
- maturity: maintenance
- function: database-driver, cli, file-system
- domain: big-data, developer-tools, microservices
- platform: go, cross-platform, cli
- tags: hdfs, hadoop, namenode, protocol-buffers, big-data-storage, unix-tools, command-line, linux, macos
