This docker image runs HDFS FileBrowser from Cloudera Hue.
- 3.9
- 3.11
- earthquakesan/ant
- earthquakesan/hue-build-env
This image is created for connecting to the HDFS cluster running inside Docker containers. To enable FileBrowser you need to:
- Enable WebHDFS in hdfs-site.xml
- Create a proxy user with a name "hue" for FileBrowser in core-site.xml
This can be done with our Hadoop docker image by setting environmental variables in hadoop.env as follows:
CORE_CONF_hadoop_proxyuser_hue_hosts=*
CORE_CONF_hadoop_proxyuser_hue_groups=*
HDFS_CONF_dfs_webhdfs_enabled=true
Your HDFS docker container should run inside the same docker network as FileBrowser. To create "hadoop" network type:
docker network create hadoop
To start the FileBrowser run the container with NAMENODE_HOST env variable set to the namenode inside your docker network:
docker run -e NAMENODE_HOST=namenode -p 8080:8088 bde2020/hdfs-filebrowser
Example docker-compose.yml file:
filebrowser:
image: bde2020/hue
hostname: filebrowser
container_name: filebrowser
domainname: hadoop
net: hadoop
environment:
- NAMENODE_HOST=namenode
ports:

image: bde2020/hadoop-namenode
hostname: namenode
container_name: namenode
domainname: hadoop
net: hadoop
volumes:
- ./data/namenode:/hadoop/dfs/name
environment:
- CLUSTER_NAME=test
env_file:

datanode1:
image: bde2020/hadoop-datanode
hostname: datanode1
container_name: datanode1
domainname: hadoop
net: hadoop

datanode2:
image: bde2020/hadoop-datanode
hostname: datanode2
container_name: datanode2
domainname: hadoop
