spark-history-cli 1.2.0

CLI for querying the Apache Spark History Server REST API

spark-history-cli

A CLI for querying the Apache Spark History Server REST API.

Prerequisites

• Python 3.10+
• A running Spark History Server (default: http://localhost:18080)

Start the History Server:

$SPARK_HOME/sbin/start-history-server.sh

Installation

cd spark-history-cli
pip install -e .

Or install from PyPI:

pip install spark-history-cli

Install as a Copilot CLI skill

spark-history-cli install-skill

This installs the bundled skill to ~/.copilot/skills/spark-history-cli.

If Copilot CLI is already running, reload skills with:

/skills reload

Then verify with /skills list and invoke it with prompts like:

Use /spark-history-cli to inspect the latest completed SHS application.

Usage

REPL Mode (default)

spark-history-cli
# or specify a server:
spark-history-cli --server http://my-shs:18080
