openLooKeng Docker Image

About the Container

This Docker image is designed to provide the following

  • An out-of-the-box single node cluster with the JMX, memory, TPC-DS, and TPC-H catalogs
  • An image that can be deployed as a full cluster by mounting in configuration
  • An image to be used as the basis for the Kubernetes openLooKeng operator

Configuration

Configuration is expected to be mounted to either to /etc/hetu or /usr/lib/hetu/etc (the latter takes precedence). If neither of these exists then the default single node configuration will be used.

Specific Config Options

node.environment

The container supplied run-hetu command, upon receiving a user-defined node.environment, will set the config property node.id to "{node.environment}-{hostname}", where the hostname is specific to the container, if node.id is not specified in the node.properties file. This allows for node.properties to be a static file across all worker nodes if desired. Additionally this has the added benefit of node.id being consistent, predictable, and stable through restarts.

node.data-dir

The default configuration uses /var/lib/hetu/data/ as the default for node.data-dir. Thus if using the default configuration and a mounted volume is desired for the data directory it should be mounted to /var/lib/hetu/data/.
