# Resource Center Configuration

- You could use `Resource Center` to upload text files, UDFs and other task-related files.
- You could configure `Resource Center` to use distributed file system like [Hadoop](https://hadoop.apache.org/docs/r2.7.0/) (2.6+), [MinIO](https://github.com/minio/minio) cluster or remote storage products like [AWS S3](https://aws.amazon.com/s3/), [Alibaba Cloud OSS](https://www.aliyun.com/product/oss), etc.
- You could configure `Resource Center` to use local file system. If you deploy `DolphinScheduler` in `Standalone` mode, you could configure it to use local file system for `Resouce Center` without the need of an external `HDFS` system or `S3`.
- Furthermore, if you deploy `DolphinScheduler` in `Cluster` mode, you could use [S3FS-FUSE](https://github.com/s3fs-fuse/s3fs-fuse) to mount `S3` or [JINDO-FUSE](https://help.aliyun.com/document_detail/187410.html) to mount `OSS` to your machines and use the local file system for `Resouce Center`. In this way, you could operate remote files as if on your local machines.

## Use Local File System

### Configure `common.properties`

If you deploy DolphinScheduler in `Cluster` or `Pseudo-Cluster` mode, you need to configure `api-server/conf/common.properties` and `worker-server/conf/common.properties`.
If you deploy DolphinScheduler in `Standalone` mode, you only need to configure `standalone-server/conf/common.properties` as follows:

- Change `resource.storage.upload.base.path` to your local directory path. Please make sure the `tenant resource.hdfs.root.user` has read and write permissions for `resource.storage.upload.base.path`, e,g. `/tmp/dolphinscheduler`. `DolphinScheduler` will create the directory you configure if it does not exist.
- Modify `resource.storage.type=HDFS` and `resource.hdfs.fs.defaultFS=file:///`.

> NOTE: Please modify the value of `resource.storage.upload.base.path` if you do not want to use the default value as the base path.

## Use HDFS or Remote Object Storage

After version 3.0.0-alpha, if you want to upload resources to `Resource Center` connected to `HDFS` or `S3`, you need to configure `api-server/conf/common.properties` and `worker-server/conf/common.properties`.

> **Note:**
>
> * If only the `api-server/conf/common.properties` file is configured, then resource uploading is enabled, but you can not use resources in task. If you want to use or execute the files in the workflow you need to configure `worker-server/conf/common.properties` too.
> * If you want to use the resource upload function, the deployment user in [installation and deployment](../installation/standalone.md) must have relevant operation authority.
> * If you using a Hadoop cluster with HA, you need to enable HDFS resource upload, and you need to copy the `core-site.xml` and `hdfs-site.xml` under the Hadoop cluster to `worker-server/conf` and `api-server/conf`, otherwise skip this copy step.
