HadoopScope

Unified Hadoop cluster health monitoring — runs anywhere, requires nothing.

HadoopScope monitors HDP (Hortonworks Data Platform) via the Ambari REST API and CDP (Cloudera Data Platform) via the Cloudera Manager REST API — from any machine, without installing Hadoop clients, Java, or any Python packages beyond the stdlib.

Key Features

  • Zero dependencies for the core — only Python 3.6+ stdlib
  • HDP + CDP support in a single tool
  • 10+ checks covering services, HDFS, YARN, and Hive
  • 4 alert channels — log file, email, webhook, Zabbix
  • Graceful degradation — checks requiring Ansible/Docker are skipped (not failed) when those tools aren't available
  • Docker-ready — full integration test environment included

Quick Example

export AMBARI_PASS=secret
python3 hadoopscope.py --env prod-hdp --checks health --output text
