Crate opendal_service_hdfs 

Apache OpenDAL™ HDFS Service

opendal-service-hdfs provides access to Hadoop Distributed File System through libhdfs for applications built with Apache OpenDAL™.

Use through opendal

Applications should normally enable this service through the opendal facade with the services-hdfs feature:

cargo add opendal --features services-hdfs

The service is available as opendal::services::Hdfs. Configure the service builder, then pass it to opendal::Operator::new.

Use with opendal-core

Add the split crates directly:

cargo add opendal-core opendal-service-hdfs

Pass a configured service builder to Operator::new:

use opendal_core::{Operator, OperatorRegistry, Result};
use opendal_service_hdfs::{register_hdfs_service, Hdfs};

fn build_operator(builder: Hdfs) -> Result<Operator> {
    Operator::new(builder)
}

fn register_for_uri() {
    register_hdfs_service(OperatorRegistry::get());
}

register_for_uri is only needed for scheme-driven construction through Operator::from_uri or Operator::via_iter.

Services that send HTTP requests also require an HTTP transport in OperationContext. See the opendal-core composition example.

For an HDFS client that does not depend on libhdfs, use the hdfs-native service.
