Crate opendal_service_webhdfs 

Apache OpenDAL™ WebHDFS Service

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

Use through opendal

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

cargo add opendal --features services-webhdfs

The service is available as opendal::services::Webhdfs. 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-webhdfs

Pass a configured service builder to Operator::new:

use opendal_core::{Operator, OperatorRegistry, Result};
use opendal_service_webhdfs::{register_webhdfs_service, Webhdfs};

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

fn register_for_uri() {
    register_webhdfs_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.
