HDFS charts

HDFS charts

Helm charts for launching HDFS daemons in a K8s cluster. Note that the HDFS charts are currently in pre-alpha quality. They are also being heavily revised and are subject to change.

Prerequisite

Requires Kubernetes 1.6+ as the namenode and datanodes are using ClusterFirstWithHostNet, which was introduced in Kubernetes 1.6

Usage

The HDFS daemons should be launched in the following order.

  1. hdfs namenode daemons. For the High Availity (HA) setup, follow instructions in hdfs-namenode-k8s/README.md Or if you do not want the HA setup, follow hdfs-simple-namenode-k8s/README.md instead.
  2. hdfs datanode daemons. See hdfs-datanode-k8s/README.md for how to launch.

Kerberos is supported in the HA setup with the kerberosEnabled option. For more details, see the namenode README.md.

There is also a HDFS client chart hdfs-client that can be convenient for testing.
