Go client for Apache Ozone

This repository contains an experimental, proof-of-concept Golang client for Apache Ozone.

It's not ready yet for using in production / non-production.

The repository contains the following sub-modules

api: the location for the generic golang api for Apache Ozone
cli: standalone executable tool for main operations (similar to the original ozone sh)
lib: proof-of-concept shared C library
python: example python script uses the shared C library
HA failovoer is missing

Status:

api
- main OM metadata operations worked well, but not all the fields are implemented
- data read / write are implemented on some level but needs further work
- security can be supported by the used Hadoop RPC implementation, but not tested
fuse
- first working POC, files are successfully listed and files can be read
- write is not implemented at all
- requires major work
shared lib / python: very basic example, poc

Testing with cli:

cd cli
./build.sh
./ozone-go --om localhost volume create vol1

Or you can install it:

cd cli
go install
ozone -om 127.0.0.1 volume create vol1

cd fuse
./build.sh
./ozone-fuse/ozone-fuse --om localhost --volume vol1 --bucket bucket1 /tmp/bucket1

Create the shared library:

go build -o ozone.so -buildmode=c-shared lib/lib.go

Modify parameters of python/test.py (om address) and run it.
