Apache Knox Chart
Apache Knox is an Application Gateway for interacting with the REST APIs and UIs of Apache Hadoop deployments. This chart is primarily intended to access HDFS from outside a Kubernetes cluster using simple REST APIs.
Installing the Chart (requires an existing Hadoop deployment)
Make sure that your Hadoop installation has WebHDFS enabled (by setting hdfs.webhdfs.enabled to true when using stable/hadoop)).
Add repository to helm
helm repo add pfisterer-knox https://pfisterer.github.io/apache-knox-helm/
helm repo update
To install the chart with the release name knox:
$ helm install --name knox pfisterer-knox/apache-knox-helm
For correctly proxying to your HDFS instance, set knox.hadoop.nameNodeUrl, knox.hadoop.resourceManagerUrl, and knox.hadoop.webHdfsUrl. Example:
$ helm install --name knox pfisterer-knox/apache-knox-helm \
--set "knox.hadoop.nameNodeUrl=hdfs://your-namenode-svc:9000/" \
--set "knox.hadoop.resourceManagerUrl=http://your-resource-mgr-svc:8088/ws" \
--set "knox.hadoop.webHdfsUrl=http://your-namenode-svc:50070/webhdfs"
Afterwards, you should be able to access YARN-UI (/yarn), WEBHDFS (/webhdfs), and WEBHDFS UI (/hdfs).
