Command Line Interface

The openLooKeng CLI provides a terminal-based interactive shell for running queries. The CLI is a runnable JAR file, so it can be run as java -jar ./hetu-cli-*.jar.

Download CLI jar file corresponding to the server’s version, e.g. hetu-cli-1.0.0-executable.jar, and run:

java -jar ./hetu-cli-1.0.0-executable.jar --server localhost:8080 --catalog hive --schema default

Run the CLI with the --help option to see the available options.

By default, the results of queries are paginated using the less program which is configured with a carefully selected set of options. This behavior can be overridden by setting the environment variable OPENLOOKENG_PAGER to the name of a different program such as more, or set it to an empty value to completely disable pagination.
