+title: "HDFS Remote"
+description: "Remote for Hadoop Distributed Filesystem"
+---
+
+{{< icon "fa fa-globe" >}} HDFS
+-------------------------------------------------
+
+[HDFS](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html) is a
+distributed file-system, part of the [Apache Hadoop](https://hadoop.apache.org/) framework.
+
+Paths are specified as `remote:` or `remote:path/to/dir`.
+
+Here is an example of how to make a remote called `remote`. First run:
+
+     rclone config
+
+This will guide you through an interactive setup process:
+
+```
+No remotes found - make a new one
+n) New remote
+s) Set configuration password
+q) Quit config
+n/s/q> n
+name> remote
+Type of storage to configure.
+Enter a string value. Press Enter for the default ("").
+Choose a number from below, or type in your own value
+[skip]
+XX / Hadoop distributed file system
+   \ "hdfs"
+[skip]
+Storage> hdfs
+** See help for hdfs backend at: https://rclone.org/hdfs/ **
+
+hadoop name node and port
+Enter a string value. Press Enter for the default ("").
+Choose a number from below, or type in your own value
+ 1 / Connect to host namenode at port 8020
+   \ "namenode:8020"
+namenode> namenode.hadoop:8020
+hadoop user name
+Enter a string value. Press Enter for the default ("").
+Choose a number from below, or type in your own value
+ 1 / Connect to hdfs as root
+   \ "root"
+username> root
+Edit advanced config? (y/n)
+y) Yes
+n) No (default)
+y/n> n
+Remote config
+--------------------
+[remote]
+type = hdfs
+namenode = namenode.hadoop:8020
+username = root
+--------------------
+y) Yes this is OK (default)
+e) Edit this remote
+d) Delete this remote
+y/e/d> y
+Current remotes:
+
+Name                 Type
+====                 ====
+hadoop               hdfs
+
+e) Edit existing remote
+n) New remote
+d) Delete remote
+r) Rename remote
+c) Copy remote
+s) Set configuration password
+q) Quit config
+e/n/d/r/c/s/q> q
+```
+
+This remote is called `remote` and can now be used like this
+
+See all the top level directories
+
+    rclone lsd remote:
+
+List the contents of a directory
+
+    rclone ls remote:directory
+
+Sync the remote `directory` to `/home/local/directory`, deleting any excess files.
+
+    rclone sync -i remote:directory /home/local/directory
+
+### Setting up your own HDFS instance for testing
+
+You may start with a [manual setup](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/SingleCluster.html)
+or use the docker image from the tests:
+
+If you want to build the docker image
+
+```
+git clone https://github.com/rclone/rclone.git
+cd rclone/fstest/testserver/images/test-hdfs
+docker build --rm -t rclone/test-hdfs .
+```
+
+Or you can just use the latest one pushed
+
+```
+docker run --rm --name "rclone-hdfs" -p 127.0.0.1:9866:9866 -p 127.0.0.1:8020:8020 --hostname "rclone-hdfs" rclone/test-hdfs
+```
+
+**NB** it need few seconds to startup.
+
+For this docker image the remote needs to be configured like this:
+
+```
+[remote]
+type = hdfs
+namenode = 127.0.0.1:8020
+username = root
+```
+
+You can stop this image with `docker kill rclone-hdfs` (**NB** it does not use volumes, so all data
+uploaded will be lost.)
+
+### Modified time
+
+Time accurate to 1 second is stored.
+
+### Checksum
+
+No checksums are implemented.
+
+### Usage information
+
+You can use the `rclone about remote:` command which will display filesystem size and current usage.
+
+### Restricted filename characters
+
+In addition to the [default restricted characters set](/overview/#restricted-characters)
+the following characters are also replaced:
+
+| Character | Value | Replacement |
+| --------- |:-----:|:-----------:|
+| :         | 0x3A  | ：           |
+
+Invalid UTF-8 bytes will also be [replaced](/overview/#invalid-utf8).
+
+### Limitations
+
+- No server-side `Move` or `DirMove`.
+- Checksums not implemented.
+
+{{< rem autogenerated options start" - DO NOT EDIT - instead edit fs.RegInfo in backend/hdfs/hdfs.go then run make backenddocs" >}}
+### Standard Options
+
+Here are the standard options specific to hdfs (Hadoop distributed file system).
+
+#### --hdfs-namenode
+
+hadoop name node and port
+
+- Config:      namenode
+- Env Var:     RCLONE_HDFS_NAMENODE
+- Type:        string
+- Default:     ""
+- Examples:
+    - "namenode:8020"
+        - Connect to host namenode at port 8020
